Yosemite on MBP Major WiFi issues?

Lubka said:
I have been trying all of that, nothing is helping.
The only solution, as I mentioned earlier, seems to be the "diagnostic mode".

Sorry to hear it: seems like there's so many kinds of WiFi problems that different things are working for different people. I got an rMBP in April and have been trying to solve the problem since then.

Sorry to hear that too.
My Macbook worked fine on Mavericks. But Yosemite seems to be WiFi- incompatible.
Same problem with WiFi on my iPad2, since I installed iOs7 one month ago.

Is Apple making fun with his customers lately? :confused:

So call in. That's useful information.

I've posted here previously :)

But after upgrading to Yosemites, my laptop struggles to connect to any WiFi network.

Luckily keychain remembered my home network so it joined that. The second issue is that when i wake my mac up i can't join any WiFi network and I have to reboot in order to get WiFI connectivity.

My home network is 2.4ghz, have tried joining a 5ghz network with no luck..

I'm a bit stuck only having my laptop work on one WiFi network.

I have no problems with sleep. I have to wonder what the hell changed that could be giving such varied problems.

Seriously, I care more about the cause than the symptom.
 
started noticing issues today.

wifi goes out and i have to restart to get it to work.

restarted twice today.. very annoying.

Oh god, they referenced us. Lol. Something something inception something.

Anyway, it is good this is getting attention. It isn't like apple wasn't taking this seriously in the first place though.
 
YES!!! Ive been going nuts the past several days wondering why my wifi has turned to sh**. MBPR mid 2012

The signal is just terrible and it cuts in an in out. My iphone seems to be terrible in the house now too when on wifi.

I had this problem early in the beta, here's the fix I've found:

1. Create a new network location.
2. Click the gear icon underneath the network service list, and select 'Set Service Order". In that list, give WiFi precedence over Bluetooth DUN, Bluetooth PAN and Thunderbolt Bridge.

I also happen to have reset my SMC and PRAM before doing these things, but I don't think it made the difference. Essentially there's a problem where Bluetooth devices become disconnected while the Mac is sleeping, and then the Bluetooth service searches for the missing device on wake. Typically it takes a minute to resolve the conflict before WiFi kicks in.

If those things don't work, just disabling Bluetooth outright might improve the situation. Hopefully this helps somewhat.

I didn't create a new network location, but did just change the service order preference and it definitely helped a lot. Was dropping a lot of packets to my router before, but things seem much better. Still get weird high latency swings on occasion, but this is much better than the 9-10% packetloss to the router I was getting before. We'll see what happens.

I also had the IPv6 link-local set, but that didn't help so much. This is on a 5 Ghz N connection.

I'm interested too. It's quite a big issue to have passed through all the builds and into the GM/public release.

My friend has the last generation 17" but has absolutely no issues with Wireless.

That's great! I'm glad it helped. I used to get the latency swings, Network Utility would show ping varying between 6-8ms and then 1,000ms for a few seconds at a time. It usually happened when the Mac was trying to refresh its list of network connections.
 
Update for some suggestions people have offered.

1) Disable Bluetooth
Tried that - no difference.

2) Set IP6 to local-link only.
Already had that setting.

3) Run with Wireless Diagnostics.
Was doing that after the problems were encountered. Made no difference.

Seems really weird to loose WAN but not LAN because in this case would be a router problem.

You may still connected to the network and yet have no access to any device on LAN.

I have exactly the same problem as mentaluproar but I tried 4 different routers and the results were identical.
Also, I confirmed that LAN connectivity remained throughout the temporary loss of WAN (with the OS X diagnostics tool running in the background and by manual pings, etc.).

The loss of WAN only would normally suggest a problem with the head end (Cablemodem or ISP) but in my case the Windows PC on the same network is unaffected and doesn't get WAN dropouts.
 
Was wondering why my WiFi was so poopy.

rMBP 13" Late 2013 model here on Yosemite 10.10. Had no issue in Mavericks but all I want is a fix. This is a problem that returns after minutes to hours and basically it messes up with Steam.
 
So far none of the solutions have worked for me, but I finally found one last night. I reinstalled Mavericks. After several phone calls to Apple, including an escalation to engineering I gave up. I need a working laptop... and a laptop without WIFI doesn't meet that criteria.

Why isn't there more media coverage?

After having read about the WiFi issue many are having after upgrading to Yosemite, I've decided to wait until the problem is resolved by Apple. But I find it curious that Apple remains silent about it, and neither MacRumors nor iMore appear to be giving this issue any coverage. Does anyone have any idea why?
 
My take on this was to make my MBA 2012 forget all my WiFi connections, recreate them, reboot the MBA and my router and now my MBA runns at normal speed (previously it could go as low as 1 mbps).
