Thread: USB dongle causing slow internet?

hi,

need deciding start troubshooting connection.

installed mobile broadband dongle , since wifi connection landline router has been running really or failing. yes it's dreaded ar5001 wifi card until working flawlessly don't want mess unless have to. there doesn't seem wrong router same behaviour occurs alternative router , laptops connect (they both have ubuntu on them too). wifi works fine under windows.

here diagnostics:


1 ) machine brand , model (pc/laptop):

acer aspire r3600


2 ) wireless brand, model , wireless chipset:
code:
$ lspci -nn |grep theros
