Why Intel 5300 wifi reduces from 130 Mbps and never goes back to that level?

2010-04-15, 14:56 PM

So I'm sitting in the kitchen, and as usual, my wireless connection speed reduces after a couple minutes after establishing connection, and never returns back to 130 Mbps. 


Transmit (currently) shows 52 Mbps... oh, now 78 Mbps, nope now 65 Mbps.


Hovering over the windows wireless system tray icon = 39 Mbps (also varies each time I check, but never gets back to 130 Mbps


Why can't it stay?  How do I get/force it back to maintain "full" 130Mbps?


I've played with Advanced Wireless Settings to keep Transmit Power level to 100%, Power Save Mode = Low,

According to Wireless COnnection Status window, I'm associated with Access point at signal strength = 80%, Signal Quality = Excellent, and

I'm connected secured as WPA AES

TAC = 5.61

BIOS 3.11

Win XP SP3

 Network adapter


Intel 5300 driver (2009-09-15)

advanced tab settings i've ensured:

Power Management = Highest (max performance)

Transmit Power = maximum (highest coverage)


What else?

This is often due to poor signal reception. Does it happen when you place the laptop reasonaly close to the wireless router?
