    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.

    HELP I CANT CONNECT TO THE INTERNET ON MY MOBILE BUT ON TH LAPTOP ITS WORKING FINE. IT SAYS WHEN CONNECTING TO MY NETWORK > OBTAINING IP ADDRESS AND ITS DOING NOTHING.
    It all happened because i changed wep encription key from 1 to 2 and now im having a lot of problems help please


  • Registered Users Posts: 1,456 ✭✭✭FSL


    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:


    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 🙂
