[SOLVED] Wireless connects to internet, but doesn't give me access to certain sites

mf93 · 10-02-2009, 10:26 PM

I recently upgraded my comuter from debian lenny to debian squeeze, and i installed the MADWIFI drivers and everything went smoothly and it showed the internet had connected, I check email fine and I access certain sites fine. However, some sites(i have found usually sites with more content to download such as facebook) not only don't connect, but don't have the wait time associated with a disconnected internet. They just immediately go to the "cannot find server" or whatever error page. I have tried a variety of web browsers, have done it with firewalls and proxies enabled and disabled, and have done it practically on top of the wireless router. My download speeds are fine(1-200kb/s) and I have no problem connecting to certain sites. So why do some sites automatically return the error message without even an attempt to connect?
p.s. sometimes there is a wait time associated with the error message
I'm using Google Chrome(or konqueror or iceweasel if you like) on Debian Squeeze with Atheros chipset using the MADWIFI drivers(ath5k is blacklisted because it was causing problems with MADWIFI)
Any help would be greatly appreciated and thanks in advance!

Check your /etc/resolv.conf file. It isn't a wireless driver issue. It is a dns issue. You may have your router used as the name server and it isn't relaying the domain names to your ISPs dns server. The ones that do work may be coming from cache.

This assumes you aren't going though a proxy the filters access to sites. Is this at home?
Are you using a dnsmasq server or running a name server?

Try to disable ipv6.
In iceweasel

Code:

about:config

in the search box type

Code:

ipv6

set it to true by double clicking

One thing I forgot to mention: also in my sources.list it doesn't resolve about half of the hosts- including ftp.debian.org and ftp.us.debian.org which are really important for many of the packages I need
I looked in my /etc/resolv.conf and this is all it said

Code:

myComp# pico resolv.conf
#Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 172.16.01
search gateway.2wire.net

This is at home and to the best of my knowledge I am running a name server
I have a linksys router and 2wire is our ISP
thank you for your help

Doesn't seem right to me

Could you give the result of

Code:

ifconfig -a
route -n
ping 74.125.79.103
ping www.google.com

mf93 · 10-04-2009, 06:26 PM

Code:

MyComp:~# ping 74.125.79.103
64 bytes from 74.125.79.103: icmp_seq=1 ttl=38 time=141ms
(this repeats 9 times)
^Z
Stopped
MyComp:~# ping www.google.com

Like i said, I recieve emails fine using KMail, and I access some sites(including all of google's search and cached pages) fine

BTW one of the sites I cannot access is linuxquestions so keep in mind that when you request output I have to manually type it from another computer.
Here is the output from ifconfig -a that is working and accesing the internet. BTW HWaddr isnt actually *** I've masked it out so I don't have my MAC address floating around the web. the inet6 is just too long...

Code:

ath0     Link encap:Ethernet  HWaddr:***
         inet addr:192.168.1.104  Bcast 192.168.1.255 Mask:255.255.255.0

for the top one on my lenny distro the default gateway was 192.168.1.1 i don't know why it isn't here

Since the connection works, and ping resolves, the dns seems OK
There is no proxy ?

Did you disabled ipv6 in iceweasel?
I had the same problem with a fresh install from SID, disabling ipv6 did the trick.

mf93 · 10-06-2009, 07:34 PM

alright I went online and disabled ipv6 in iceweasel and now I have full access in iceweasel! I then went and followed teh directions for disabling it systemwide but I still get failed apt repositories and chrome doesnt work...when i lsmod i get clean results like I should

Code:

PC:/home/me# lsmod | grep ipv6
PC:/home/me#

however this shouldnt return anything but it does...

Code:

PC:/home/me# ip a | grep inet6
    inet6 ::1/128 scope host
    inet6 fe80::224:2bff:fe7d:744f/64 scope link
PC:/home/me#
