PLease help. Wireless problem
Problem: New computer, (see specs below) has really shoddy wireless access. However, my netbook and my laptop, placed in the same location as the PC have excellent wireless performance.
Troubleshooting so far:
1) Speed test on netbook and laptop give 4mb/sec speed download, 384 upload. On PC i get the 384 upload, but speeds vary from 3 megabits to 512 kilobits. Strangely though, my bittorrent performance is excellent... i get 3.6-4mbit peformance.
2) Ping test (continuous 1024 bit pings: ping -t -l 1024 192.168.1.1) on netbook give average of 3 millisecond return time, with no packet loss. on PC it gives an average of 40 ms, varying from 3 millisecond to 200 millisecond. Also, some timeouts occur (about 1% of the time).
3) dB meter test (Inssider) says netbook recieves -75 dB, while in the same spot as PC, which recieves from -85 to -90 dB.
4) Netbook is XP, laptop is Vista, Pc has run all three (now is 7). Problem has existed constantly (under xp it was worse).
5) This is my 3rd PCI wireless card (has 3 antennas, says it's Xtreme and by all means should get a better signal than my lowly netbook), and all 3 have been placed on both PCI slots. Device manager has said they all work fine.
6) Did I mention this has been a nightmare?
7) There are few sources of interference, one of which was my bluetooth mouse and keyboard... but the problem persists with them gone, and I've changed the wireless channel from 1-11 without change.
8) I ran out of ideas, and came here for HELP!!!
So, I beg and implore you, community, to help me get this solved. Please... I'm gonna go mad.

first guess - you have those antennas mounted on the card, next to the metal case. not up in the clear air. case is shrouding and blocking the antennas.
good guess. i also thought of that, so i turned the case towards the AP. The antennas are now facing the AP, yet the problem persists. Also, i placed the netbook behind the PC (shrouded by the case from the AP), and i was getting better signal than the pc...
The wireless antennae on that card are fairly standard types and do unscrew themselves sometimes. It may just be worth checking that they're all properly tightened?
I'd also look again at the channels piece. Are you seeing more wireless networks on the new card than you are on the laptop. THe router is a wireless G router, and I'm assuming laptop and netbook are probably G as well. Your new card is N and so will potentially pick up other networks that your G kit can't see. If you're in a busy wireless neighbourhood it may be worth sifting through to find a channel with less stuff on?
Sorry that's all I can think of, unless you've got some weird software installed on your new machine that's doing some sort of QoS piece and reserving bandwidth?
