issues with wireless network; takes long to access internet

[santiagorf]

I started having problems using internet on a wireless network on one computer.
When I boot up, I can connect to the wireless network right away, but it takes from 10 to 15 minutes to use internet. Once I'm able to use internet, it works flawlessly until the next reboot. I haven't changed the router settings, but I have been having this problem for about 2 months. This is the only one computer that has this issue.
Some information:

It may seem counter-intuitive, but before you start taking apart your system and patching it, try rebooting your router. I know you said other computers work fine with it. Try it anyway, power it down (and your modem too while you're at it), take a smoke break even if you don't smoke, then power them back up. Then power up the computer in question and see if it's fixed. Many times this will work, if it does it saves you a lot of time & trouble. If not it costs you ten minutes or so.

Thanks for the advise; I tried it, but I still have the same problem.

Hi santiagorf,

I had similar problems and refused to believe the problem was with the router configuration because all other computers and smartphones worked just fine. But my work laptop always had connection problems with this wifi.

I suggest you to follow this guide on How to solve internet connection problems. Pick the sections that fit to your problem, and apply it one by one.

In my case it was the items 1.6 (set a fixed channel) + 2.5 (set to G-only). You will find complete solutions overthere. Try it out!!!

Obs.: By the way, that site is awesome. Maybe the owner is here in this forum too. His site has helped me a bunch of times.
