Thread: I already connect to the wireless but cannot load any web pages

i installed ubuntu 11.10 in pc week ago, , wireless network works until yesterday.


when turn on computer, have wait ~30 minutes before can connect website. think pc connect internet, can see “signal bar” on upper right corner, whenever opening website, gives me this: (btw, using our school's wireless)


*********************
connection interrupted


connection wireless.csu.edu interrupted while page loading.


site temporarily unavailable or busy. try again in few
moments.
if unable load pages, check computer's network
connection.
if computer or network protected firewall or proxy, make sure
firefox permitted access web.

next use “ifconfig”, here information,

1 thing notice that: number after “rx packets :150” in eth1 keeps increasing, until becomes larger (like 3000), wrong information gone , can see webpage. problem is: takes ~30 minutes reach larger number.


, then, “ifconfig” give me this:
