Hi everyone! Would be really glad if you could help me.. I have mbp late 2008 (10.7.5, 5,1) and (newlly installed) wifi connection 50 mbps. But I can't get speed above 20-23 mbps on wifi. On ethernet cable it works fine. On ipad3 it works fine On 2006 mbp it works fine! (all tested in same room) I've tried: 1) Remove and Re-Add The WiFi Service 2) Reset PRAM (Command, Option, P and R keys before the grey screen appears) and SMC (Shift + Control + Option keys and the power button at the same time + power button 5 sec with no cable or battery) 3) change all possible router settings (2.4 to 5 Ghz, tried all channels). But since other devices work fine, I assume that the router is not the problem 4) restore priviliges (I've read somewhere in the web that it could help) It just seems that it has some sort of speed lock. Could it be such thing? Or there are any other ways to resolve that issue. Thank you very much!!!
