and the card I am dealing with is Realtek RTL8191SE
theres an Atheros card too but thats for wired connections...
Prior to all of this everything was working ok other than a overall lack of speed (due to 2 laptops, 1 wireless bluray player, 2 game systems, and 4 cell phones on the wireless network. but of course not everything on at the same time.)
Ok Me and my wife decided to upgrade our internet speed from 20mb/s to 30mb/s. We contacted our ISP and was told that in order to do this we needed to upgrade our modem from a DOCSIS 2.0 to a DOCSIS 3.0, which was ok by us. The service was connected by them, but we saw no speed jump out of anything including speedtest.net. We had a service call and got a new modem (cisco DPC3825) wireless modem. When the tech left we had the speed tested on my wifes machine and got anywhere between 27-33mb/s download and 2.8-3.1mb/s upload. Right about where advertised (i know wireless has a bit of fluctuation to it so this was totally acceptable) then I decided to get on mine and try it out and right away I get 28mb/s average, with both running it was around 20 which is good too. Then I started doing stuff on the internet (youtube, netflix, etc) and I kept have to wait on buffering. Puzzled I ran the test again and found I was at 5mb/s or less with 2.7ish up speed while her computer still keeps the 27-33 range. So I tried all the classics like reset the modem, reboot the computer, reset the network card, I always get the same result...It will run at the speed it is supposed to for a little while (could be 2 minutes could be 5 min. tops) then slows back down to a crawl. I have tried TCP optimizers with no help, i have tried "clean boot", nothing, I have tried network troubleshooter, and it finds nothing wrong, I have double and triple checked that my drivers are up to date, I have adjusted the power saver setting to keep it on always. I have been through my system with MBAM, trend micro house call, and avast scanner and all have found no virus or mal/adware. used microsoft's system integrity checker and all is good there. I know it has to be with the card but don't know what to do. Maybe I am missing something Hope you guys can help, you have before and I thank you all the time.
Please help in anyway possible
EDIT: almost forgot I ran the ping test and when I ping my modem, I get 1ms, 36ms, packet loss, 105ms (those are the average of 4 tests run back to back. Also when wired into the modem through an ethernet line i get the full 27-30mb/s all the time no matter how long its there. Maybe that will help a little
