EXTREMELY SLOW wireless network transfer speeds

[CheerUpEmoKid]

ok so, i'm trying to transfer a movie from my laptop to my dad's laptop. i'm getting stop and go speeds at 20-60 kb/s.

i can't seem to figure out what's going on here. the movie is only ~3.2gb. and it's saying its going to take over 5.5 hrs

i can't remember what kind of speeds i used to get through my network, but a file this size used to take roughly 2-6 minutes

both laptops are wirelessly connected to the network, one running win7, other running winxp

i realize i could use a flash drive, but that's not the point. these transfers never used to be this slow. i'm on a 20mb/s connection

anyone got any ideas?

ps, i'm positive both machines are clean, no viruses/spyware/malware etc, no firewalls blocking any traffic, all that good stuff

tried port forwarding, flushing dns, no torrents running, disabling AV/firewalls

this current issue is transferring from win7 to winxp, but it seems to be a problem with all computers on the network, windows7 and winxp

20mb/s doesn't help much... What wireless are you running? 802.11 a or b or g or n ?

Why not connect them with wires and get 100 mb/s. Antivirus will slow it, wireless encryption will slow it also...

You're most likely getting wireless interference. A sudden change like yours usually means the addition of new wireless signals in the area, such as new cordless phones in the home or a neighbor who just installed their own wireless router. Run Wireless Net View (scroll down for the download link) on the laptop and look for a channel that is not being used as much as the others (only use channels 1, 6, or 11 if possible). Change the channel on the router to that channel and see if the connection speed improves.

ok so i wasn't completely sure on the wireless mode, so i checked and this is what it says:
"Mixed accepts 802.11b and 802.11g connections"

i don't wan't to use wires because i don't wan't to run wires along the floor to my laptop

i've tried disabling my AV and firewalls, and the encryption is disabled

i never thought about checking this before, but after checking it now, there are only 2 wireless networks in range around here, mine, and another distant encrypted network. my network is on channel 6, theirs is on 11.

i should mention that there is one cordless phone, iphone, wireless xbox 360 adapter, 2 desktops, and 2 laptops all wireless usually running at the same time. could all of these be causing interference, and greatly slowing my speeds?

it's just for wireless network transfers, when i'm browsing websites or downloading my speed is not affected
