WiFi is connected but unable to access internet in RHEL 6 and Fedora 17
 

Hi All,

I'm facing this issue since I've installed RHEL 6 ( exactly same problem in Fedora 17 as well). My WiFi is connected perfectly, it also shows my SSID in Network Connections (under Wireles tab)but as a matter of fact I cannot access anything, nor internet neither my router pager.

When I check Connection Information (by right clicking on wireless icon in top right)I see all information which is necessary for a connection to establish. My internet works like a charm when connected via wire, no issues at all.

Please advise, what could be the reason for such a behaviour?

Kind regards,

Can you post the results of an 'ifconfig -a' as root?

here is the output of ifconfig -a as root. I'm also attaching screen-shot for your reference

Yeah, odd, everything looks like it should on first glance. Admittedly, I'm at work so don't have any Unix/Linux boxes to verify anything. Are you able to ping your router/switch even?

I'm unable to ping the router as well :( ... I've attached a txt file, which maybe helpful in resolving this issue. Please advise.

Hi,

Just to keep everyone posted here.. I've upgraded from RHEL 6 to RHEL 6.1 and Wifi is working absolutely fine now. I'm able to connect to internet, can ping the router. The change that I've noticed is, there is a "ifcfg-Auto_belkin.7ad7" (Auto_belkin.7ad7 is the name of my Wifi connection) file in /etc/sysconfig/network-scripts, which i never saw in RHEL 6 when I was struggling to make WIfi work.

Cool. Good to hear it got settled, because I hadn't a clue what it could be (don't use RH myself despite having went to the trouble to get certs for it).
