Wifi USB modem Intermittent 105 errors Win7 64Bit

I have frequent intermittent 105 errors DNS Server not found. I run a Laptop, Win7 home edition 64 bit, Telstra TEHS_0c280c 3G usb Modem, I live 600 metres from Repeater and have consistant full WiFi strength. I have had this error using both Google Chrome and Internet Explorer.

When this error locks me out of the net, it is very frustrating as I have to reboot the laptop and reset the WiFi modem several times before the problem comes good. Sometimes this can take up to a full day as I can get the Net back and then have the 105 error again, and other days I will not see it at all. This prob has been driving me nuts for months.

Thanks in advance for your time and input. Cheers Pete

ps Remedies I have already tried to no avail :- CCleaner to both remove cookies and clean and repair registry probs. And Defragging.

  2. Hi, and thanks for your post. I did what you outlined above. everything is working ok, but I will have to play the wait game to see if this error happens again. I will post again in a couple of days, the error would normally occur in this time. Cheers Pete
  3. Ok,hope it keeps running!
  4. Hi again, It lasted one day and I had continious 105 errors for two hours the next night . Once this prob happens it is hard to rectify, mainly because I cant work out where the prob is at. When I do windows diagnostics it says no probs. when I do wifi diagnostics it also tells me it cant find probs even though I am looking at the yellow triangle attached to my sys tray wifi symbol. I also did repairs with one of the diag. programs and the triangle clears and the wifi status says connected to the internet, but as soon I try to activate a web page through my browsers (IE or Chrome) I go to sleep watching the circle arrow spin backwards. the first error I normally get is timeout(118) then I try again and 105 does its routine as previously explained (:

    I am not new to computers but I am new to wifi and windows 7. I am at a loss with this frustrating extremely intermittent prob.

    thanks again Pete :cry:
