WiFi Problem

[thierrz]

Hi all!

So I installed Mountain Lion today and love it so far, but have an issue with my WiFi.

After upgrading to Mountain Lion I have the following issue:

It connects to my WiFi, recognize all the settings (ip adress, router adress etc) but it won't load web pages or get internet acces.

I made an WiFi hotspot using PDAnet on my iPhone (which is connected to the same WiFi Router) and then it does work!

I never had this with Snow Leopard or Lion.

Is anyone familiar with this problem?

Thanks in advance!

i have the same problem: macbook pro, middle 2009, tp-link router. I've tried lots of settings, nothing solve the problem. I changed the router to my old asus router, and it's working… slowly, but i have net. with snow leopard and lion never had a problem.

ive been having this problem with the Gold Master since it was released and have yet to find the solution.

WMM is already switched on...Ive changed channels, frequencies, Tried constant pings to googles dns, created new netorks..

Nothing works.

Im not back on Snow Leo and its flawless on 20mb again.

Its really p*ssing me off

I have a tp link router too, same prob

Everyone else with packet loss using a tp link router?

 

[Nailist]

Yeah it's TPLink.

Upgraded the TPLink firmware, and the 90% packet loss is now 0%.

Still can´t get it working...

Strange enough it's working fine on my work. Cisco hotspot. With my experiabox @home it won't.

Works!

This fixed it for me, thanks to WiZzi!

A short explanation:

1) go to http://192.168.2.254
2) Username: KPN is filled in already, Password is blank, or you changed it before, then log in using your password.
3) Go to Network at the top of the page
4) Go to WLAN at the left of the page
5) Use these settings:
Enable WLAN: Yes
Mode: IEEE 802.11g Only
Channel: 7
Transmitting power: 100%
Enable WMM QoS: No

Wifi problem solved

Hi!

This works for me: reset your mac's PRAM and SMC (on macbooks).

PRAM reset:

SMC reset:

After these steps no need to hack your router.
