I have the EPC3925 set to bridge mode. Never had a problem with it. This morning nothing connects to the internet and my AirPort Extreme router is reporting "Double NAT". I try rebooting both devices, changing modem to router mode and back again. Nothing works. Then, just as suddenly, the router reports everything is fine and the internet is back. Anyone have any dea what that might have been about?

UPC have reported issues in several areas in Dublin- and if you're in Dublin West- there have been severe power surges in the Lucan/Clondalkin areas. Burglar alarms going off all over the place.

I'm so glad I have surge protectors.......

Anyone know how I can enable WPS on my Cisco EPC3925?
I can't enable WPS (it is currently set to DISABLE and is grayed out, not allowing me to change it to ENABLE).

Anyone know how to fix it?

Edit: Very odd, after just clicking around in the menus for around 15 minutes, it magically changed to ENABLE and is no longer grayed out...

The reset button is just over from the cable input into the modem- hold it in for about 5 seconds. Once its reset- the default username:password combo is Admin:password - you should be able to set it up to your requirements.

The manual for the modem is here

Yeah I know how to log on to the interface.

I can edit everything but the WPS settings.
Now that it has switched itself to "Enable", I am unable to revert it back to "Disabled".
This is very odd, as I am able to edit all other settings such as the encryption key, MAC filtering etc...

It's just like it is locked in the firmware for some reason.

ryanch09 · 13-08-2014 9:02am

Apologies if this has been asked about already but it's doing my head in and I'd really like a solution.

We're currently on a 30Mb connection from UPC and have the EPC2425 box. For some reason we can't get above 21/22 Mb/s over wireless, on any of our devices, when plugged in via Ethernet we get about 31 on an average speed test but due to the location of the router Ethernet is not really an option.

Has anyone experienced this themselves and know a fix?

Thanks

Because the wireless just isn't as strong and that's as good as you're going to get unfortunately. I'm sure there are others here who can explain it better.

But that's a good as you'll get.

srsly78 · 13-08-2014 10:28am

The fix is to setup your own wifi hotspot, and connect this to the upc box. However wireless will always be inferior, it's bandwidth gets shared between all clients and is subject to range and interference etc.

Can anyone help me with how to block Google DNS on EPC3925 ?

Which option do i have to use ?

ED E · 21-08-2014 11:07am

Why would you want to block google DNS? You'd need to bridge to a proper router to have that kind of functionality.

Keith C · 21-08-2014 8:22pm

I've just moved from 30mb epc2425 to 60mb on technicolor tc7200. Since I changed the reception on some channels (tv3) in particular is pausing and making a high pitched sound.
Is this problem caused by new modem?

macade · 12-09-2014 1:54pm

Anyone knows what is happening in my laptop?

I've recently got 120Mb broadband from UPC, but my laptop (and my laptop only - the rest of my stuff is fine) don't seem to follow up. I had 12Mb and it was way faster than now. It fails to load youtube videos, etc. It is making me so stressful.

I've already checked for any updates, changed DNS server (when I hit run -> cmd -> ipconfig /release -> ipconfig renew, it rocks a bit for a few minutes, but then it goes slow again), turned the modem off and on again... I really do not know why this is happening.

I have a Dell XPS 15 4370, everything is up to date, my antivirus (MS Essentials) is a-ok. If it changes anything, I also have an iPad, two nokia lumias (710 & 920) and an old laptop (and my Dell was the last one to get connected).

Does anyone knows what the heck is going on?

srsly78 · 12-09-2014 2:06pm

Your laptop probably has an old wifi adapter, so the speed sucks. Do test via cable to confirm.

Or maybe the laptop just has the worst signal for some reason, and other devices are hogging the bandwidth.

I don't if it is so. When I had the 12Mb speed, it was perfectly fine, much more faster than how it is now.

Also- with all the other devices- it could well be that the wifi router you're using could be falling back to the lowest common denominator.

You can upgrade the Wifi card on the Dell fairly easily by the way- replacement cards are about 20-30 quid on ebay (make sure you get a compatible one though)

Then do a test with an ethernet cable- and see if the wifi is the bottleneck.

Also try changing the speed/duplex settings for your network card.
Hard to guide how to when I do not know your computer set up, but have a look here htt p://community.spiceworks.com/topic/308025-manually-change-duplex-settings

Try the different settings and see if there is any difference.

jrby · 15-09-2014 2:45pm

Hi, I think I have a 100mb package with UPC. My pc is on the wireless network and today at lunch the speed was 54mb. Is there any point in moving to the 200mb package? will i notice any difference. I do a fiar bit of gaming, battlefield etc

ED E · 15-09-2014 2:47pm

Not unless you want to connect an ethernet cable.

jrby · 15-09-2014 2:50pm

pc is in the wrong part of the house, unfortunately...

not worth upgrading then?

Not really you could set the Cisco to bridge mode and buy a new wireless AC band router and fit an AC wireless card to the PC ( if it's not a laptop) and you might make some speed gains or go with some powerline plugs, but tbh 200Mbps might be a waste

jrby · 15-09-2014 3:01pm

thanks.

so from a wireless perspective, is the limiting factor the wireless card in the pc or the modem?

srsly78 · 15-09-2014 3:08pm

Both. There are so many factors that can limit wireless speed. Firstly note that the wireless bandwidth is split between all clients, so any smartphones or tablets in your house will eat up bandwidth.

Just buy some powerline adapters and connect your pc through those. You should not be using wireless for gaming at all if you care about connection. Also setup QoS on router to make sure other users don't effect your latency.

Could be both if it's an older PC it probably has a wireless G band card, which would be slower to N or AC, problem with N is that depending how far you are from router and if you have solid blocks and other items that might block the wifi signal speed will be reduced or switch back to G mode, thus slower speeds. If you have a smart phone you could download ookla speed test and see what speed you get in the room with the Cisco router and see if it's the sane speed as the PC.

keegobytes · 18-09-2014 1:56pm

Hi all,
what would be the better Modem EPC2425 or EPC3925. I have 100mbs from UPC, but it dose'nt seem to boost to far so I set up a TP-link extender in the house and I highly recommend it, just one extender nearly cover the the whole house, but the UPC modem I have is a EPC2425, and it does,nt extend enough, it gets to my TP-link and shows 2bars recommended is 3bars......

keego???

srsly78 · 18-09-2014 1:59pm

You should be connecting your routers via ethernet cable or via powerline adapters. Do not connect them via wifi - this is known as a wifi repeater and just cripples the entire network.

Also do not rely on 1 wifi hotspot to cover the whole house, it just won't work well (unless your house is very small and has paper walls). Much better to have 2 hotspots providing coverage.

Annnnd even more: do not use b/g/n mixed mode (unless you have a proper dualband router). Set up a seperate network for wifi G devices. And lastly - setup QoS on your router or you will never have good performance if there are multiple heavy users.

Gadgetman496 · 18-09-2014 3:06pm

The EPC3925 is the best of the two you mentioned

Thanks for the info srsly78 but cant make out the last bit ( b/g/n mixed mode ?, wifi G devices?, setup QoS ..) Im just an ordinary wifi guy.... but thanks all the same.....

Thanks gadgetman, have to say i'm impressed with that tp_link extender TL-WA850RE boosts 300mbps.

If I could get the EPC3925 I might get an extra bar or two out of it its worth abash...as I mentioned im no genius at this but thanks for the info....

srsly78 · 18-09-2014 3:23pm

Are you connecting the routers via cable? Your post gives no indication as to how you have set things up.

Should look like
upc cable -> upc cable modem -> ethernet cable -> second router

Just buying a good router won't make everything perfect, you still need to set stuff up. You might want to use bridge mode and stuff like that, but this is where it gets complicated. UPC are awkward as you MUST keep using their router, you can't just swap in your own. All the upc routers suck

QoS = quality of service. This is feature offered on many routers that allows bandwidth allocation between users. Very important for gaming, so other people don't lag you out.

The EPC3925 is capable of achieving higher speeds and has the bridge option available through its menu's. If you could get one from UPC (for the higher speeds) you can simply use your own 3rd party wireless router to provide great wireless to your entire house.

Snake Plisken · 19-09-2014 1:20am

lads have this for a couple of years now, but I've noticed every couple of days the speed drops down from 200Mbps to 3Mbps, a reboot of the router sorts it out, but if it continues and turns out its not on the UPC side and they have to replace the modem, what are they sending out? I don't have TV with them just phone and broadband, so don't want the horizon box, I want a router similar to this one which I can switch to bridge mode.

Same rubbish unfortunately, but brand new.

I have the exact same issue, UPC offered to replace the router with a brand new one... Same model though

//edit: Oh the irony, just as I was typing this, internet froze.

PopTarts · 27-09-2014 12:58pm

Hi

I have the 2425 router and am trying to change the wireless password from the original.

I don't have a laptop, anyway to change it via my phone or IPad?

I tried logging in to the 192 address but get a HTTP 401 - Unauthorised error saying I must enter correct username and password.

Thanks

coldfire1x · 30-09-2014 12:26pm

Need a quick suggestion. I have the Horizon Box. Last couple of days the wireless has gone off, however I can connect via cable and get the internet.

Called UPC and they tried to reset the modem on the box remotely but that didnt work.

They are giving me 2 options now, take a new Horizon box or take a seperate modem / router.

I am not sure which one should I go for. Anyone knows the exact model number of the model / router they are sending out now?

Any suggestions?

Hello all,
I`m having very similar issues to this and have received no satisfaction from UPC at all. I`ve even went to the lengths of restoring my laptop to its original factory state just in case I had done something wrong somewhere with my settings, but I`m still having the same issue. I`ve had an engineer out twice. The first time he replaced the technicolor modem with the cisco modem and I was quite happy. Unfortunately I started experiencing slow speeds and needed the engineer to come out again which he did however when he connected hard wired to the modem was receiving the required speed that I`m paying for (120mb). I connected my own laptop and also received the same speeds so we both thought excellent its working and I`ve just wasted the mans time. However after he left my speeds disappeared again. I checked my wired speeds wit upc speed test this morning now and got over 100mb and then tested immediately with 2 other "independent" speed checkers and received an average of between 1 & 3 -4 mb. I get the feeling Upc`s speed checker is somehow making it seem like you are getting the promised speeds when in fact you are getting the ridiculously slow speeds. I then tried to download a file to see if the readings may have been wrong and therefore proceeded to download a file of 2MB, that`s M not G and it was saying estimated download time of over 20 mins.. I mean come on. Can anyone ANYONE at all please help me as UPC dont seem to care as they get there money regardless until my contract is up which thankfully is in 2 months time.

Calibos · 05-10-2014 11:22am

You'll never get anywhere near the 120mb over wireless, only over a gigabit wired connection. The speedtest.net servers can get hammered depending on time of day and depending on which of the nearest servers from the drop down list you select you can get wildly varying results.

I use the UPC checker and download a well seeded torrent and it maxes out my 120mb connection so I personally trust the UPC checker.

After moving my routers one time I inadvertently shorted the coax feed to the modem introducing a load of electrical interference to the line. My speeds reported on the UPC checker showed a huge drop indicating to me that it's a reliable tester.

I have bought and ethernet cable, but it won't work at all. I have tested it on another network, and it went just fine.

Seriously, what the heck is going on with my UPC modem?

SkySter · 20-10-2014 8:36am

I have an EPC3925 operating in bridge mode. After several months of reliable operation it stopped working on Thursday last. I made no changes to my configuration.

First thing I tried is to reset the modem back to defaults and activate bridge mode again. No Joy. I do not seem to be getting a public IP address anymore. Also when I go to 192.168.100.1 I cannot login. It won't accept the id and password I setup. In the end I reverted non-bridged with two subnets and my Asus router in the DMZ. Works now.

As to the cause, the only theory I have is that I noticed I am subscribed to the UPC free wifi service. I wonder if this breaks bridge mode? Anyway I have unsubscribed and will check again once it is reversed. It takes 72 hours apparently.

If anyone else has similar issues please let me know?

Dave..M · 20-10-2014 9:12am

have you been migrated to IPv6 by any chance? Check your public IP via one of the what's my IP sites or run a speedtest.net and check your external IP in results.

Nope. The IP is still IPv4.

DesperateDan · 07-11-2014 8:19pm

Hi folks, I've noticed that any time I kick off some torrents, our old upc modem drops the connection and actually kicks everyone off. It always comes back after about 2 mins, like it's rebooting itself almost. Has anyone else noticed this?

Modem is flawless if I don't go near it with torrents, long runs of netflix etc. are just fine. If I turn on uTorrent everything is fine for about 15-20 mins but it's almost guaranteed to start disconnecting us after this time. Then it fairly consistently kicks us off if uTorrent is left on.

ED E · 07-11-2014 8:31pm

You're overloading it with too many connections, a decent router can handle this no problem, but not the bargain basket stuff UPC ship.

If you go into your settings and limit simultaneous connections to 50 or less it should hold for ya.

Gadgetman496 · 07-11-2014 8:44pm

Have you all the settings in uTorrent for DHT disabled? They should be.

chichaglisha · 17-11-2014 3:51pm

hi everyone,

ill try to explain my problem the best i can. i have a cisco epc3925 router/modem and a PC and a NAS (Zyxel NAS325) and a small 5-port GBit switch. and a fujitsu laptop but i use it over wireless 99% of the time
1. connecting PC to router gets me 10Mbit connection
2. connecting NAS to router gets me 1Gbit connection
3. Connecting PC and NAS to switch gets me 1Gbit speeds from/to NAS, switch is connected to router so it forwards the DHCP - BUT the switch only get 10Mbit towards the router so both PC and NAS still have a slow internet conenction, but at least i get to copy stuff back and forth form PC to NAS at some acceptable speed
4. just to try it out i have also connected laptop to router by cable and i get 1Gbit

so i tried a combination where everything is connected to router and one where i conenct everything to switch and then the switch to router. PC and switch always get 10Mbit no matter what i do (towards router) and NAS and laptop always get 1Gbit (in any combination). all cables are 1Gbit cables, tested numerous times. i just cant believe that this router is not compatible with an Intel chip on my motherboard........or what else could it be ???? the switch is some cheap chinese model but it worked perfectly well with a FritzBox that i had in another apartment where i had 1Gbit everywhere. No issues with internet whatsoever, router delivers without problems. no issues with wireless. router is new, maybe 1 month since i got it so i guess it has the latest bios but i can check later today

any ideas what could be the reason for a drop down to lowest speed ? anything that i could do about it ? i cannot find an option to force the speed and duplex on the router or how to connect to console to try to hack it. changing settings on ehternet card in windows does nothing....tried linux mint and centos7 and they both show 10Mbit so i guess its not the drivers.....im really desperate atm, thinking about switching the cisco for a FritzBox but what if this happens again ?

ED E · 17-11-2014 5:01pm

You can't replace it. You can't really configure it.

Sounds like an MDIX issue, are the cables straight or patch?

AngCork · 25-11-2014 8:54pm

Getting very slow speeds at the moment with my Horizon service, 200 mb my arse! Speedtests are showing very low download speeds, upload seems to be ok though

Wolfbrand Morro · 03-12-2014 8:42pm

Hi all,

Just recently got the Horizon box and I've been having regular connection loss to the extent that every 2 days the internet is unusable for anything more then loading a webpage, and even that takes about 5-10 minutes. This is a network wide issue, ethernet and wifi at a multitude of ranges. Any ideas what's causing this and any way to fix it?

Korasa · 05-12-2014 12:48pm

Hey lads. Got the 120mb package off of upc there about two weeks ago and I could not be less pleased. Constant mini drop outs and straight up disconnections are the least of it. The speed is variable at best anywhere from 15-45 mb on a good day and instances where it simply won't work. Trying to do college work is difficult and don't even try and play a game or something. We received the Technicolor TC7200 modem and I am curious as to whether it is that causing the issues? Seem to be a lot of complaints about technicolor products in general online. After factory resets and calls to tech support I am at a loss. Anyone have similar issues? how did ye bypass them?
