internet disconects and is slow.

do you have any other 2.4 mhz devices in your room that might be interferring like a cordless phone? something in your room is interferring with the signal. What other electronics do you have in yoru room other than your computer?

Two of the most frequent causes of poor Internet performance are spyware and viruses. Spyware can slow your system by interfering with your browser and monopolizing your Internet connection. Spyware monitors your Internet use and keystrokes, which adds delays. The problem is compounded when there are multiple spyware programs running at the same time. If the problem is severe enough, you can lose connectivity altogether. To get your Internet performance back, you should regularly run an antispyware program to clean out any spyware infestation.

I decided to post here even though it was an old thread. I suspect there will be others that needs this tip. I had the same issue and was trying to figure out the cause. had tried everything else, removing homegroup networking, unistalling drivers, updating drivers, you name it and found no working solution as of the date of this post.

My wired connection using this same laptop was blazing fast, but the wireless connected with speeds similar to dialup. I finally decided to disable my router security which was initially set as WPA-PSK to see if it made a difference. All my other laptops and PC's worked with this authentication so I initially didn't think it would help. But guess what, as soon as I disabled the router security it was blazing fast. Apparently the Broadcom 802.11n wireless modem in my ACER laptop doesn't support WPA-PSK very well. I changed my router to WPA2-PSK, which is more secure by the way, and it likes it. I'm having to more problems with slow wireless on this particular wireless card. I suspect it will work for you too. Good luck.
