Hi, i have just bought a Acer Aspire 5750 and set it up only to find that my WIRELESS is running at 5.5mbps where my other notebooks run at 75mbps. The speed is still fast but i would rather have it running at full speed. I have been reading up so many pages on how to fix the issue with no luck. I have a Broadcom 802.11n network adapter and running a netcomm N150 modem. My older Acer works fine and my toshiba also works fine both running a 802.11n adapter . Does anyone have a cure for this???any HELP would be much appreciated
Make sure your Wireless Transmit Power is set to "Full." and that your Power Saving Mode is set to "Off."

I have noticed that some wireless cards modify their link speed based on the activity of the wireless connection. I have an Azurewave Atheros AR9285/5895 card which when idle has a connection speed of 8.0Mbps, but when downloading a movie, goes all the way up to 150 Mbps.I have tried the power options, mine are slightly different to the realtek ones but its still the same.Update of whats been done, i have reinstalled windows 7 HOME premium. I uninstalled network adapters and reinstalled them, i have played with power settings and various other settings. Still sitting at 5.5 mbps. 75 mbps?! You might wanna check on reviews or comments online for users who bought the same model regarding the wifi connection.If you have a WARRANTY or a repair deal take it in and have them check the wifi card antenna connection my niece had the same with hers and now it works GREAT her antenna was loose not even connected
