Hi Bruce and chev65.
My son has a brand new PC with Intel i5 processor, Gigabyte motherboard and some big GeForce grafics card. It works smooth and fast. Except if we talk about the wireless internet connection. The net adapter is a Digitus card with an RTL 8185 chip on it. The PC is running Windows 7.
Its behaviour is as random and strange as Bruce describes it. And no chev65, I am sorry to say that the latest Windows 7 driver
on Realtek's own website does not help one bit. A good suggestion though but I already tried it.
When the PC starts up it is just fine. I can open up 5 tabpages on an Internet Explorer and run videos from youtube on all 5 whilst reading the news on tabpage 6 and stream live tv on tabpage 7. No problem at all it seems. That just works like that for a while. In fact for such a long while of maybe 15 minutes that I declare "systems are go" to my son and 5 minutes later it sucks. If you click on anything or start up a new browser and key in an url and hit enter it will bring up the first ikons and banners fast enough but that is just the cashing showing itself. The real contents of the page just wont show itself for minutes. It just swirls that blue circle on and on and on. Even if I restart the PC it will not help. Maybe for just 1 minute and then be slooooooow again.
My sons says I have to kill it completely and start up from dead cold. If I do that then yes it works for a handful of minutes and will soon be annoying again. I have uninstalled the drivers
and installed them again. I have let Windows 7 find the most suitable driver but also tried out some drivers that I pointed out myself. The name on the netadapter card is Digitus but Windows says it is a Realtek just like Bruce sees. I have tried disable and enable. It just do not want to be stable.
If I grab my Asus laptop and sit in the same room as my sons PC and surf on the internet then there is absolutely no problems on the laptop. My laptop runs Vista. My colleague has the same laptop and he upgraded his Vista to a Windows 7 and he does not have any problems with the wireless either.
The signal strength indicator shows at least 4 out of 5 bars and the Realtek utility tool shows a signal strength of 85% and a quality of that signal to around the same 85%. The IP-address is there and it also says that there is a connection through the router to the internet. Even if I cannot get anything on an internet browser or maybe just a few bits and pieces before it gives up with "page cannot be found" then I can still open up a command prompt and ping different DNS-names for newspapers, the tv-station website, yahoo, youtube and what not. But it will not download an html-page with full contents.
I tried to use Google Chrome and Internet Explorer. When it runs ok for 20 minutes in a row it goes real fast and it seems ok but at any given moment it will give up.
I have looked through the setup on my router to see if there is anything in there, which could be interesting. I turned up some numbers on different stuff and changed the frequence a bit but I did that just out of dispair because as I said: No problems anywhere in the house except my sons new PC.
What is the best course of action? Throw the netadapter card through the window of my dealers shop ( I doubt it is heavy enough for that purpose ) or do any of you guys have some suggestion that I did not think about?
