can't acces internet after about 24-36 hours uptime

hi, i have an anoying problem
i acces the internet via wlan, but after weveral hours uptime i can't it, web browser says "connecting.." but nothing happend.
only restart solve the problem, so the router is ok
i have broadcom wlan card, and i use networkmanager, tried wicd but the same problem.
restart networkmanager, and reload broadcom driver module can't help (tried brcmsmac and wl)

[bazsi@dell ~]$ lspci | grep Net

Re: can't acces internet after about 24-36 hours uptime

From the output you posted, your connection still seems to be perfectly functional at the time.

Next time the issue occurs, see if you can fetch the content of a webpage (lets say Google) with something else than your normal browser (another browser, curl,...).

Re: can't acces internet after about 24-36 hours uptime

it appears to be ipv6... most ISPs don't yet provide ipv6, so typically it can safely be disabled.

https://wiki.archlinux.org/index.php/Ipv6#Disable_IPv6

I disabled mine, as comcast in my area does not yet provide it, though they are apprently implementing it slowly.   You may want to check if your ISP serves that up though before doing anything crazy.
