    That looks normal. Can you run 'ipconfig /all' instead of just 'ipconfig'?

    Again nothing obviously wrong there. Right ! Time for the scattergun approach to troubleshooting ;)

    1.Check that the laptops work okay when connected to the router with an ethernet cable
    2. Verify that the Win7 & Vista laptops can connect to other wireless networks.
    3. Turn off all other wireless devices and try one laptop at a time on your wireless network (jut in case one of devices is interfering in some way)
    4. Change the SSID & key on the wireless router and try again (in case the laptops have saved some odd settings related to the current network).
    5. Change the security (e.g. WPA, WPA2 etc.) and encryption type (TKIP etc.) on the router.
    6. Change the wireless channel on the router (it's probably on 6 so try 1 and 11).
    7. Try this tip from DrunkMonkey on another thread

    Right so.

    Used to have a wired eircom router which i connected to a belkin wireless router to broadcast my broadband to PC laptop and iMac.

    Upgraded to an eircom wireless router to save clutter. I set it up using the cd with my laptop.

    On iMac it connected automatically (once I entered the security key on the bottom of the router) but when I connect on my laptop the connection says local only and I cannot connect to the internet :(

    Please help!

    Hi,

    Mine is set-up using WEP (I know you said it's bad)...BUT I have the MAC option also set-up. Is it secure enough with BOTH WEP & MAC or should I change it?

    WAP can be cracked , it may take longer ( a few more minutes ) but can be cracked .

    Yes, change it. Your average user can crack WEP. Takes a little more cunning to spoof a MAC (Most won't bother or know, but still a risk)

    Its WPA ;) Your right it can be cracked but you significantly increase the time if you take words outside the dictionary. WPA cracking is currently based (Mostly) on precomputated tables such as RainBow or Look Up tables. So if your password was say "dublin" it would most likely fall in seconds. However if your password was "dub1n_g34@7" it would not appear in a rainbow table and hence forth a requirement to brute force would be required. That password would take a very long time to crack. There are new methods using packets and vectors like the original WEP attack, but from reading up on them, they are still taking quite some time to fully crack WPA. Remembering also that WPA has variants such as WPA-PSK and WPA2.

    Its important to note however that any password system will eventually fall with enough computational power behind it. So the stronger you make your password, the longer it will take.

    Don't forget to turn on WPS ;)

    I mean OFF! http://www.tacnetsol.com/news/2011/12/28/cracking-wifi-protected-setup-with-reaver.html

    Also WPA can still be nuked using Amazon's Cloud and a bit of tegra support. Spend 10 to 20 euro and there is a good chance you'll murder the password within an hour

    I think WPS is off by default with the 2247, I was able to crack the password for my own 2247 using reaver in a very short space of time, it is actually very clever how it works but not so clever I want anyone to use it on me :)

    To the OP, and I appreciate this is an old thread, but technology was not even advanced then as it is now, a 56 character WPA key is complete overkill, and it certainly would not need to be changed every three months.

    Even with a ten character alphanumeric cryptic password (one containing letters and numbers, not incluyding special characters (*@?!/), something like stUwu4afAd, it would take a single PC 579,299 years, 10 PCs working collaboratively years 57,930, 100 PCs 5,793, and 1000 PCs 579.

    Please note these figures are a few years old, but not old enough to make much of a difference when you are talking in terms of thousands of years.

    Otherwise great post :D

    Agreed alright but RainBow tables and look up's have become a lot stronger too. WPA2 and your grand these days, at least in a residential environment. As you said yourself, its only a fire door that will withstand so much. The initial thread was merely to get people away from WEP! :)

    Yes, I concur, it is a good thread :)

    The article I was reading before I came across it talked about how using very long overly complicated keys might discourage regular users from using even rudimentary security or a decent 10-14 character password and I thought it was a valid point.

    Have you WPA2 on your 2247? It's actually my girlfriend's so I have to take another look but it is running the latest firmware from Eircom as far as I am aware which we downloaded here:

    http://broadbandsupport.eircom.net/download/netopia/firmware/

    I heard about raindbow tables a few years ago but never got to try them because I just did not have the hard drive space.

    Have you tried reaver on your own WPS yourself?

    Also, I have a query about individual client bandwidth on the 2247 here: http://www.boards.ie/vbulletin/showthread.php?t=2056905343

    Try using a simpler key e.g. dublinwifidemo124% and see does that work.

    Would make sense. Windows at a guess? Was most likely not updating the saved password so it was trying the old password when your router was using your new password.

    Firstly you shouldn't be using wep it's useless. Use WPA2 with a pre-shared key which is reasonably long and doesn't consist of dictionary words.

    When you changed the key did you put the new key into your mobile device or is it still trying to connect using the old key?

    Like FSL said, follow the first post and get WPA up and running. Use a simple passcode.

    Just fixed it , i basically putted the key to 1 again from 2. By the way, I Use Wep and its alright, i sometimes get disconnected out of no where, but if i set it to security WPA would i have to do a really really long password just as mentioned in the first post in this thread?

    You don't need a long password. Something memorable but very random is good enough:

    dublinwififorme - Bad

    d8bl1nw1f14m3 - Good

    du&^nw1q8l!?1 - Best

    Hi,
    Has anyone installed a Radius server and used it with the Zyxel router?
    Would the WPA2 authentication type then appear under Security Mode? At the moment, only WPA-PSK & WPA2-PSK are available.

    Thks,
    jfg

    p.s. The link http://www.soroban.co.uk/wepkeygen.htm on OP's post no longer works.

    Yikes. Blast from the past on this thread.

    Why are you using a radius server? Is it home based? Unless you are using it in an office, I would consider it overkill to be honest.

    If you wanted to go down that route, I'd suggest getting some flexible gear that supports all the features most consumers don't want to know about. I'd check out https://www.ubnt.com/, their stuff has some good plug and play features.

    The info on this thread is going back 4 years , so I'm wondering if the same advice applies for security settings on an Eir box? (residential)

    The options from the router menu, I've in included in this screen shot:


    Screenshot 2021-11-29 at 16.03.46.jpg

    Couldn't find any info on the Eir site regarding enterprise encryption.

    Is WPA2 Personal still considered the best protocol for residential users in 2021?


    Cheers 🙂
