Can ping but can't view web pages

I am trying to get wireless working on arch linux.  When I connect with ethernet everything works perfectly.  But when I connect over wifi I can successfully ping other hosts, but firefox says I'm offline,  Does anyone know why that might be?

If it matters, I'm using xfce.

Hi, are you able to ping ip's only, or does google.com also work?

If it's not a DNS problem, post more info first, ifconfig iwconfig /etc/resolv.conf

What do your domains resolve to?
Try using wget, if they resolve to 1.0.0.0, you have a DNS problem.
What router do you have?
Modem?

Yes, I can ping IPs as well as sites like www.google.com

This is the output of wget www.google.com

bash-3.2# wget www.google.com

Resolving www.google.com... 74.125.45.99, 74.125.45.103, 74.125.45.104, ...

I'm assuming this means it is not a DNS error?  This is the output of ifconfig iwconfig /etc/resolv.conf

In firefox: File->Work offline (uncheck it)

Re: Can ping but can't view web pages

ifconfig and iwconfig are seperate commands, since it doesn't seem to be a DNS problem you can forget about /etc/resolv.conf. Also, how are you connecting to wireless?

Re: Can ping but can't view web pages

ping but no major network traffic? looks like a scaling issue. Try adding net.ipv4.tcp_window_scaling=0 to your /etc/sysctl.conf and force sysctl to re-read its configuration (sysctl -p).

Re: Can ping but can't view web pages

Editing /etc/sysctl.conf didn't work- I guess it's not a scaling problem.

jryarch, I don't exactly know what you mean by "how are you connecting to wireless," so I'll answer you by saying that I'm using iwconfig wlan0 essid "insert unsecured router name" and then dhcpcd wlan0

still no work

Re: Can ping but can't view web pages

Did you try string's suggestion?

In firefox: File->Work offline (uncheck it)

It could be as simple as that. I would also try another web browser to make sure it's a Firefox issue.

Re: Can ping but can't view web pages

Well .. he can "wget http://www.google.com" and this pretty much proves that: 1. DNS works; 2. he can connect, send, receive data to/from remote (internet) servers listening on port 80. + looking in the original post: "firefox says I'm offline".

DjMaxx: is it *actually* saying: Firefox is currently in offline mode and can't browse the Web. ?

Re: Can ping but can't view web pages

Yes it is, and now it works.  Problem solved.  What's sad is:  I looked for a setting on firefox and couldnt find it- obviously because I was lazy, tired, or just too dumb.  Thanks everyone, and sorry to put you through this.
