Howto unlock your Eircom F1000

Dermot McDonnell · 23-01-2015 2:38am

@Dust,

The ZyXel boot loader for the F1000 is not attached to this post as .bin files are not allowed.

Google are not so fussy so it is here.

I would like to thank Eircom for including it in their sources

and you for your input, I shall try to make my admittedly nerdish unlock guide more accessible.

Cheers n good luck!

Thanks, I will complete later today.

I get that MAC further down I get b from the sticker on the back of the router but how about the first MAC entered closer to the beginning of the guide. Do we all enter the same as you for some reason or do we get from somewhere else? I ask as I know MAC addresses are supposed to be unique identifiers...

Let's clear up the appearance of various MAC addresses in the unlock/upgrade process.

First MAC is encountered with this command:

ATWZ EC43F6470F58, 01, 01, 00, 0C

The principal purpose of this command is to set the Engineering Debug Bit. Once set it stays set and allows you to enable write access to flash at will (via ATBT 1). You can use any MAC address here as it will be overwritten during flashing.

Once you complete the flash, the MAC address is again reset to a generic value built into the firmware. Use the ATBP command to enter actual F1000 MAC address from the label on the back of the F1000. Of course, you can put any mac address you wish.

Keep us posted on your efforts, please.

Good luck, Dermot.

Great support, and for free, thanks again.

Apologies if this has been asked already, but does unlocking the modem have any impact on eVision boxes connected to that modem?

My speeds with the Eircom firmware are ok, but I'm having problems with the modem dropping LAN and Wifi connections, and having to reboot the modem, even though all looks to be ok on the main page (connected ok etc.). Only Skype traffic works at that point, everything else gone. Very strange, maybe the newer firmware would fix this?

@PauloMN, I have eVision also. The firmware upgrade will fix those problems you describe These are precisely the issues most other people experience. I restart my VDSL connection regularly as I need to test updated F1000s but one friend has >100 days uptime - no disconnects, reboots, or dropped wifi/lan connections. He also has eVision.

Okay done! :cool:

Well bootloader installed and I flashed the 12th image from the link. I am just about to update the settings for Eircom and set 802.11 n.

So can I take it you would like me to run and post results from a stock f1000 and my modified one of speedtest.net over LAN, ping results over 100 pings on wireless n and wireless g, and maybe a screenshot of the connection information when we log into the WebUI?

Let me know.

Well done! How was the experience?

You can get the latest firmware directly here. It is a released firmware, not a beta. It does have the slight drawback that it supports only a single telnet session into the router at any given time. Network gurus like multiple telnet sessions so that they can extract very detailed xDSL data to analyse their ISP performance. If you want to do that, you need a slightly earlier firmware. There is excellent information, and software, on how to do serious xDSL network analysis in various threads here. Look for the VMG8324-B10a threads as that is what ZyXel call the F1000.

Carry out whatever tests you feel appropriate. The System Monitor - xDSL Statistics report would be good for connection information.

If you are a gamer, it would be nice to know if it makes much difference. In particular, where you have multiple human players over WAN and/or Wifi.

Increased F1000 reliability and performance is the goal. It would be nice if an individual with chronic F1000 problems were to do the upgrade and report here.

Good, yeah. It was not too bad at all although I am employed in and study networking, and in my personal spare time I work on technical things, like hacking my Samsung TV last week so it will let us switch between RTE Player and iPlayer, 4OD, and ITV, without having to reset and change the region setting back and forth between Ireland and the UK.

That is not to say anyone with less technical experience cannot do this! On that note, there are a few things minor things not in the guide I had to think about, some silly mistakes I made, and documenting them should help others. I will draft that for you over the next few days and you can add to yours if you like.

So, on performance, I am connected now with the hacked router. When trying to sync the DSL light went from flashing green, then to amber, and then Internet red while it was setting up authentication. I never noticed the F1000 with an amber light before but it may well be normal, especially with the new firmware.

After that the Internet went green indication authentication was achieved although strangely the DSL light has stayed amber. The Eircom F1000 manual only mentions the normal DSL off, flashing, or on, nothing about amber. Although it appears to be working fine, any idea what this is offhand? I am on call at the moment so I have not yet looked for an official Zyxel manual.

My devices are all now connected on 802.11n - without 60/70% packet loss, there is now 0% packet loss thus far, which was my main motivation for doing this. I had to run on 802.11g prior to this. I was getting about 95mbps down over LAN to speedtest.net which is now 96mbps, same latency of 15ms. LAN upload speed to speedtest.net has increased by ~ 5mbps which is great. Before hacking I also had to frequently reboot the Zyxel so time will tell if that is now resolved.

Over Wi-Fi, in the same room although not directly in front of the router, I was getting around 26mbps down, this is now between 35mbps and 48mbps which is a great increase of up to 100% although should I not be getting speeds closer to what I get over LAN, even in the same room as the hacked router, considering 802.11n has an absolute maximum limit of 300mbps?

Interesting, although right now I want to see how much better I make performance. For that, am I right I would be better with the latest from zyxel.it?

I am but I only built a decent gaming machine before Christmas and have not been playing much online since our recent fibre upgrade. I can document any latency differences to servers for Rust or CS etc no problem.

I consider not being able to use 802.11n and the frequent reboots, maybe once every two days or so, a chronic problem, at least hopefully it was

Thanks again.

Dermot McDonnell · 23-01-2015 8:18pm

@dust,

Amber (yellow) DSL light indicates VDSL, Green is ADSL. Eircom do not distinguish.

Excellent news on WiFi n up sync rate. I expect most people who do the unlock will get similar benefits. It's nice when the F1000 just works quietly in the background. I recall well the months of frustration that drove me to devote the time and effort to unlock the damn thing.

I realise wifi falls short of the theoretic max, it may be worth trying 40MHz channels to see if that helps. At least now it is far better than it was yesterday. Perhaps further development by Zyxel will improve matters further.

I use the latest firmware as it is not a beta.

Keep us posted. I will pm you re updating the unlock guide.

Your input greatly appreciated. Bon chance!

runswithascript · 23-01-2015 8:25pm

The link to Zyxel Italia is requesting a password?

Also, is your DSL light amber like mine and do you experience speeds higher than 50mbps using 802.11n on your router over WLAN?

@dusf,

apologies, I replied on my tablet and deleted half of my last post. I put the Dec 14th, 2014 Zyxel released firmware,V100AAKL7C0, on google. The B10 you refer is a couple of releases earlier. ZyXel Italia is unreliable, it goes down for days sometimes.

Amber DSL light means you have a VDSL sync, Green means ADSL. Eircom do not distinguish on their firmware.

runswithascript · 23-01-2015 9:33pm

Thanks for clairfying. I have just uploaded that firmware and after reboot no improvement on WLAN speedtests over 50mbps although from LAN I am still getting 96mbps.

Can you please let me know whether you achieve speeds above 50mbps with this router in 802.11n?

murphaph · 24-01-2015 9:07am

Great thread. Dusf...have you ensured your client device is n capable and also switched off all other wifi clients during testing? AFAIK the whole network will operate at the max speed of the slowest connected device.

Yes, definitely n capable as they would not connect when the WLAN is set to n only otherwise. Although it seems counterintuitive the speed would be decided by the slowest connected devices, I will wait until everyone is awake here and then test. I know I could do it with MAC filtering but I will just wait.

What I have done is enable channel bonding. The channel band was set to 20Mhz and I have now set it to 40Mhz. If anything this has decreased the speed. In order for this to work the devices need also be capable of receiving wireless n at 40Mhz rather than 20Mhz. I have read this is restricted on UK devices which may explain no apparent speed increase at 40Mhz. There is a tablet from the US here I can test with later.

In the Wi-Fi options there is also a setting to limit the WLAN speed which I left blank. I noticed earlier it also notes that a limit will be set automatically if none is set manually. I set it to 100mbps but this made no difference.

FTR I have scanned and our WLAN is the only one on any of the channels, I have tested in front on the router but two metres from, cordless phone powered off from the mains, and the router is on a table and not near a fridge or any other electrical equipment. I will try again later with all other devices powered down.

What speeds are you guys experiencing with the Wi-Fi set to wireless n only, hacked and/or unhacked?

@dusf, sadly not, there are a couple of legacy devices here that don't do 802.11n unfortunately. Using Mode N only certainly helps if you are able to select it.

captain_boycott · 27-01-2015 12:50pm

Thanks Dermot for unlocking my device - great service, i'm especially grateful for the fast turnaround!

I got no improvement whatsoever in vdsl connection speeds. I never realistically expected there to be anyways, and I suspect that anyone reporting better speeds is really seeing better performance on Wifi rather than any improvement in line speeds. I use a separate AP for wireless to take advantage of external antennas, so i just disable the wireless on the F1000.

But the good news is that port forwarding - this is my reason for unlocking - now works!! And i can now keep updated with bug fixes/updates from ZyXel so happy with unlock.

It is good to have further confirmation port forwarding works on the unlocked F1000. Eircom acknowledge on their forums that port forwarding does not work on their F1000 firmware.

I had big issues with Port Forwarding since the F1000 ports closed every time the router reboots or reconnects to the xDSL, a not unfrequent occurence. I know a number of retailers who could not monitor the CCTV in their premises from home. The upgrade to recent Zyxel firmware fixes that. My F1000 uptime now exceeds 100 days.

@Captain_Boycott may wish to comment since he too has been having port fowarding problems, now resolved by flashing a recent firmware.

Hi!

What firmware version are you currently using?

As my TTL cable should arrive tomorrow, I'm wondering which version I should download and flash (it's not really clear to me which ones are beta and which ones are stable).

I suggest the latest firmware linked in post #64 above, it is officially released by Zyxel and is not a beta. I have no reports of problems with it and have been using it since release. If you require multiple telnet sessions, as discussed in that post, then you need this.

I updated to this firmware and the difference is noticeable. I freely admit that I would love to unlock the router entirely but haven't a clue how to to do it. I'm lost straight away when I attempt to follow the guide, I'd be shot if I sent the router away for a day:pac:.

Hi Dermot,

Finally getting around to trying this, I have the following cable:

http://gruvin9x.com/shop/electronics/24-usb-to-uart-ttl-wires-serial-cable-pl2303hx.html

I have communications software set to the correct baud rate etc, but i dont see anything when i boot up the router. I don't think i'm connecting the TTL cable correctly, so based on my cable which has red, black, green and white, which colours go in which pin on the board?

eddiem74 · 28-01-2015 10:25am

What an amazing way to start the day... got an email from Amazon (ordered my TTL cable at amazon.co.uk last Friday because that's usually fast and reliable) saying that my order couldn't be delivered and has been returned to them.

I must've ordered at amazon hundreds of times, never got any problems and now my USB TTL cable doesn't arrive, for whatever reasons. argh!!

Do not use the Red (5v). Black is Ground, it should connect to Pin 5 - also Ground - on the serial header - see the pic in the first post. Green is Tx (transmit), it should connect to Pin 3 Rx (receive) on the serial header. White is Rx (receive), it should connect to Pin 2 (transmit) on the serial header.

@eddiem, sadly, afaik, there is no way to know in advance how xDSL will improve. Generally sync rates increase, sometimes by a lot, but not always. You wifi performance will certainly improve, especially if you use wifi N only. Expect 100%, or larger, increase in wifi throughput - some people get much more than 100% extra. VOIP and Port Forwarding all work. Regular reboots and xDSL resyncs will become a thing of the past.

Ok so black (5) green (3) and white (2). I tried that combination last night, couldn't get anything on the console to show up.

I used extraputty, set the com port to what was detected, baud rate to 115200, 8bits, no parity. Bottom left showed as online but couldn't see any text when i booted the F1000.

It boots the eircom OS normally but I just can't see anything from the putty console.

Afraid not, I'm sorry to say. Once the pins are connected correctly and Putty is correctly configured, the boot sequence should appear on your screen as soon as the F1000 is powered up.

Double check your Com port number and settings. Make sure you have handshaking set to None. If you dont succeed PM your address and I'll mail you a spare USB TTL device I know works - I have a couple of spares here.

The xmodem file transfer of the bootloader from the PC to the F1000 is failing. When you execute the ATUB command on the F1000, it waits for the PC to send the bootloader via xmodem. Your PC app must have option to send a file, the bootloader in tghis case, via xmodem. You have several seconds after the ATUB command to kick off the transfer. Sadly, I dont have windoze so cant sent a useful pic.

Thanks for the quick reply!

After a few attempts I realised that I had to send the file manually, about 30 seconds after the file transfer began I got the exact same error. I will try again tonight.

How's wifi and sync performance?

Hi Dermot,

I'm not sure yet, its for a family member so i will test it this weekend.

I used possibly an older version of your pdf guide saved locally on my laptop, i didn't see the line you'd written in more recently about erasing the eircom settings until i had finished, is that still required:

"CFE> atbr <- Erase Eircom settings and you're done.
Erase persisten storage data? (y/n):y"

Oh ok so you're on "V100AAKL7C0", no problems in the 6 weeks you've had it no?

Reseting the F1000 from the GUI will achieve the same result. Maintenance -> Configuration -> Reset.

None.

rogercross · 30-01-2015 2:53pm

I've also made the changes you had in screenshots for eircom, now when i hook that up to the line for the first time this weekend is there any additional settings i need to enter to make it work with eircom's efibre service?

For Eircom, the only default VDSL setting that needs to change is VLAN 802.1q must be 10. The F1000 will sync automagically, DSL light should go AMBER, and Internet light Green.

rogercross · 30-01-2015 4:00pm

Excellent, thanks for all your help on this Dermot.

I'm curious to see what the difference will be now using this new firmware, an initial positive is the web management interface behaves much more smoothly compared to eircoms custom interface.

Quite a few. See the latest firmware changelog linked earlier in this thread. One difficulty is it that it is impossible to know what, if any, fixes and updates Eircom apply in their releases as they do not say. However, they still include the 038 xDSL PHY, for example, while the more recent and much improved 039 PHY was released by Zyxel well over a year ago.
