Windows 7: Poor Internet connection over WiFi

Poor Internet connection over WiFi

Hi everyone,
I'm having this problem with the WiFi (which I set up in 2011) at my grandfather's. I googled quite a bit for this problem and never found a solution. I've had the issues for quite some time, but as I usually only stayed there for a couple of days the last couple of times anyway, I didn't spend too much time fixing it. Now I'll be taking care of him for a week, and I'm here for a total of almost 2 weeks. The Internet connection is very poor - sometimes, web pages will load (but not as quickly as they should), sometimes they will load after about 1 minute, sometimes they will load about halfway and just not go any further, and sometimes page loading just gets stuck at the beginning. There is never any message such as "the server timed out" of "the server could not be found". The problem only happens on my computer (Lenovo ThinkPad X230 Tablet with Intel Advanced-N 6205) - I've seen at least 10 devices at various times using the Internet without any issues, including his laptop (thank goodness), and my computer doesn't have this issue with any other wifi network (the router is a Tenda single band Wireless-N W268R). I don't have the problem when I connect via ethernet, but the ethernet connection is only available upstairs, and I want to be able to stay downstairs when I need Internet on my computer, because he can barely make it up the stairs. I can also access the router settings etc. without any issues. Here is what I've tried (although it could well be I don't remember evening I tried), in no particular order:
  • Forgetting the network and reconnecting
  • rebooting the router
  • Forgetting every single WiFi network the computer has ever connected to (after copying all the profiles to my memory stick), including the profiles in another place - I forgot where that was now
  • Setting the network as a public network and back to a home network again
  • ipconfig /release and /renew
  • ipconfig /flushdns (or whatever it was that clears the DNS cache)
  • using a different browser
  • rebooting, again and again
  • looking through firewall settings
  • temporarily turning off the firewall and trying to use the Internet, still doesn't work
As I've said, Google didn't bring me any luck, and I'm really confused with this issue. It could be that the connection between this computer and that router never worked. Does anyone have any ideas as to what in the world is going on here?

Hi trainman, Welcome to Seven forums.

Try to upgrade the router's and your NIC firmware.

1- Change wireless router encryption to WEP, rather than WPA. (I understand switching to WPA2 could also help with some compatibility issues...)

2- Uninstall router management software that came with router (e.g. D-Link router comes with a program called “Network Magic”. It might interfere with the Windows-7 wireless software that is already installed)

3- Change wireless adapter settings: In "Properties", unclick "TCP/IPv6"

4- Change wireless adapter settings: In "Properties/Configure", disabled Ad Hoc QoS Mode.

5- Change wireless adapter settings: In "Properties/Configure", changed Wireless Mode to 802.11g

6- In Control Panel/Power Options: Change advanced power settings... Wireless adapter settings: set to Maximum Performance

Alright I upgraded the router's firmware, and that somehow did it. I still have no idea why this happened, but it's working now. Thanks for the help, and happy new year!

Glad the issue is resolved. Firmware can be a major cause for low speed or any other issues.

Happy new year to you as well.
