Wireless totally broken in 5.0rc4?

Tue Nov 23, 2010 9:12 am

Hi there, i just upgraded my lab AP to 5.0rc4 and now wireless with encryption (wpa/wpa2) does not work at all.

Clients can connect but then i just get a "group key exchange timeout". I am not able to connect a client (i tried 4 different ones).

I also did a reset-configuration on the wireless settings and even definied new security profiles but without success.

Anyone else expiriencing this also?

Regards,
brainy

on a different note, why do you use TKIP? use AES, it's faster and more secure.

just a thought - WPA with tkip was cracked in 2 hours as a demo on some hacking conference. AES add several weeks to that time and WPA2 several month.

WPA2 AES is crackable in days with a PSK

WPA or WPA2 key could be cracked in days or weeks instead of years.
Cool, nice to know

The best wireless security you can have is a SSH tunnel!

Some hardware encryption acceleration so we dont take a performance hit running it and yes!

I try to not post links to distributors, but this company already sells 10Gbit RouterOS routers: http://www.mikrotikrouter.com/2200.asp

Haven't seen anyone complain.

Wrong thread I think Normis?

Also they appear to be 10 x 1gbit ports standard, not 10gbit :P

with a passphrase like that, sure... anyplace I setup, the passphrase is either from uuidgen, or something like pEbE93=9FExu+ega

Although, it sure would be nice to have WPA2-RADIUS built into MT... ;)

I had to downgrade to 5.0rc3 because wireless/encryption is totally fucked up in rc4 :(

i had a lot of clients there weren't able to connect to the AP anymore

i have a "old" client that only support WPA and not WPA2 but neither with TKIP nor AES i am able to connect with rc4

after the downgrade everything is fine again .. :(

WPA2-AES PSK worked for me on my 433s, but not WPA2-AES-EAP.

Hi. We got a problem with 5.0RC4, and rolled back to 5.0RC3.
Setup: Windows 2008R2 AD, NAP ( Radius) + Mikrotik 411AR with 5.0RC4.
Wireless setup - Access point wtih two SSID:
1) WPA2 AES EAP (Radius auth)
2) WPA2 AES PSK (preshared key)

When I install 5.0RC4, Windows 7 clients with Radius auth. can not connect. No errors on Windows 2008R2 NAP server.
Second SSID with WPA2 PSK works ok.

please do not say stupid things ... breaking a string of 8 or more characters take several years .. because the method works by comparison (dictionary), even when using pre-compiled tables with the help of the graphics card processor. As long as the admin does not choose a simple word like "hello1234" or "administrator" :lol:

I know a few people who would disagree with you based on experience, Also Mr Rainbow Tables would like a word with you also.

Wireless security is a joke, Run real encryption on the top of a link
