I am having serious WiFi issues on my MacBook Pro (retina Mid 2012 with Yosemite) where the connection continuously drops making Internet impossible to use.
I have already tried all of the options described on various blog posts, including Fix Wi-Fi Problems in OS X Yosemite.
The problem is only happening on my MacBook Pro. While everything works fine on my MacBook Air, PC Win8 and two Android phones.
The router (UPC Ubee EVW3226) is set to:
2.4 GHz
802.11 bgn
WPA2/AES
Bandwidth 20 Mhz
Channel Auto
Beacon interval 100
DTIM int. 1
Fragment Threshold 2347
…and all other settings as recommended by Apple in Recommended settings for Wi-Fi routers and access points.
These are the devices I have:
MacBook Pro (WiFi drops all the time when laptop PC is on)
MacBook Air (works perfectly)
Lenovo Laptop with Windows 8 (works perfectly)
Android Phone 1 (works perfectly)
Android Phone 2 (works perfectly)
The problem actually only seems to happen when the Laptop PC is on, which makes me lead to believe it might be an issue with interference (though it's strange that it doesn't affect the MacBook Air (which is in the same room of the MacBook Pro).
I am getting really frustrated with all this and not sure what to try anymore. Does anyone know if there is a solution apart from switching to Ethernet?
