built in wireless lan card (help) boost or bust

I think I'm in the right place. I bought a pre-packaged system from best buy 3 days ago:

Dell studio xps 8100
Win7-64bit
Intel i7 CPU 860 @ 2.80GHz(4 of em i think)
8GB DDR3 memory
ATI Radeon HD5770 graphics (1GB)
Dell 1505 wireless LAN PCI-E card and 802.11n mini card (802.11b/g/n)

...don't know how much more ya'll need as far as info on my system?

After getting it up and running, I tried to play a MMO game...and had very noticeable latency issues(pings going from 30 to 12,000)(even on lowest graphic setting)....where i had none before on an older system (wireless/hp media center/vista/3gb ram/256 Graphics card).

I disabled the built in wireless and pluged in my old linksys usb wireless conector. Afterwards I did not notice any latency issues.

Is the Dell 1505 not a good wireless system? With the N band available does it inversly effect the G signal? Why does it go strong for 3-5 mins then crap out for 30-40 secs?

Is there something that I can do to "boost" the Built in wireless, or at least keep it more consistant without the ups/downs?


also...in my search for a solution, I did a bit of research and noticed that the Graphics Card to the system I bought specifies a 450watt power supply; however, the package spec'd in a 350watt. I thought this was the issue before I checked the usb wireless signal/consistancy.

Should I just return the system, or is the wattage not an issue and the built-in can be fixed.

Thanks in advance, opinions and shots are welcomed.

The specs for the 5770 show a 450 watt PSU requirement and that is the minimum for that card. Pretty cheesy on Dell to skimp on the PSU like that. Besides that obvious problem, I would make sure you have all the Windows updates for your system.

additional details:

the signal bar for the internal card is usually 3-4 bars while the usb adapter is 2-3 bars. So the internal card seems to have a better signal, Could it be the Power drain from the graphics card is causing the wireless card to "slow down", but doesn't effect the power needed for the usb device?
