Wireless problems (slow connection/drop outs)

okay, im gona try and keep this short.
im new to fedora, but not so new to linux, still very much a noob, just not a total beginer.

ive got f13 installed on my netbook, and the speed and overall beter-ness? of it made me want to get it going on my desktop.
ive installed, and have updated the kernel, and network manager (Along with a few other things)

my problem is this; after about an hour or two i get a drop out, unable to reconect.
untill i use 'ifconfig wlan0 down > ifconfig wlan0 up' then it works great for about 10 minutes, slows down, and eventualy drops out. i updated networkmanager in the hopes it may have been that, but it really made only a slight difference.

iwconfig :

$ iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:"**** you!"
Mode:Managed Frequency:2.462 GHz Access Point: 00:1E:2A:0E:08:50
Bit Rate=54 Mb/s Tx-Power=18 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
Link Quality=32/70 Signal level=-78 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0


im useing a linksys wusb54g > chipset ralink rt2510? (dont quote me on that its from memory)
im also using WPA encription, i am currently messing with those setting to see if that helps.

Re: Wireless problems (slow connection/drop outs)

You might be experiencing what is called a black hole router. Here are a couple of links I pulled up on a quick Google search.

Re: Wireless problems (slow connection/drop outs)

whether this is the problem or not, its still very interesting lol
thank you!

i get this problem with my desktop (runing f13 with kernel update)
but not with my netbook (runnign same f13 with kernel update)

?
could it still be this "black hole" problem?

your idea does make really good sense though, cause when i go to smaller websites (say google?)
it really isnt that slow.
but when i call for larger website that involve more/larger packets? , it bogs down.

Another possibility is IPv6. You can try disabling it.
