For those running Yosemite - Has 10.10.1 solved the Wi-Fi bug?

[naltst*]

I have a brand new Mac Mini running Yosemite which seems to have some wifi issues. I never got over 1Mbps using a 2.4GHz network which is a real shame as my girlfriend's laptop can't do 5.


Connectivity speeds from broadbandspeedchecker.co.uk (I appreciate these may not be direct comparisons)

Frequency Mode MacMini iPhone 6
2.4GHz Up to 54Mb/s 0.917 5.27
5 GHz Up to 54Mb/s 7.56 14.76
2.4GHz Up to 144Mb/s 0.395 10.33
5 GHz Up to 144Mb/s 27.87 36.55
2.4GHz Up to 300Mb/s 0.016 0.01
5 GHz Up to 300Mb/s 53.03 or lose connection entirely!! 27.75

What's going on? Why is my iPhone consistently quicker than my mac?

Edit - can't make this look like a table
tl;dr - 5GHz is quick but sometimes breaks, 2,4GHz is super slow

Hmm.. what would be helpful is the specs of your WiFi card. Card Type, Firmware Version, and PHY modes supported(802.11 x), and what it is negotiating at at the router.

This would go for everyone who has bad/poor/no WiFi connectivity. somewhere there has to be a common link. So if everyone could post that, that may help.

Like this?

I'm not having any wifi issues but I did with Mavericks and it was resolved by renaming the 2.5 and 5ghz networks. My ISP recommended syncing the two wifi network settings but a senior 2nd line support for Apple asked me to rename and unsync network settings. Worked first time and no wifi issues since. Helped iPad 2 and 5s wifi too.

I also stopped getting the 'appending of a number to my computer name' issue and that hasn't re-occurred even after moving to Yosemite. Thought I'd mention it though this might not resolve the issues for everyone.

rename and unsync network settings.

I'm not sure I know what you mean by this... Can you explain?

Aaaaaand, it choked hard waking from sleep. So not 100% fixed.

ARGGGHHHHH

I work in higher ed and have been pushing hard for people not to update after what we saw in regards to wifi from early adopters.

That there seem to still be so many problem after 10.10.1 is not heartening!

I wish people reporting issues were a bit more specific about their hardware.

Given the WiFi issue is Yosemite-specific, I think it is possibly related to additional BT usage due to Handover - would be worth anyone having issue to try disabling Handover, not BT and see if the interference with WiFi becomes more normal.

BT always interferes with WiFi as they share the same band, usually WiFi doesn't get seriously impacted due to the relatively light BT traffic volumes.

OK, both my 2.5ghz and 5ghz wifi networks have a name, which in my case was the name of my router. My ISP is BT and they recommend syncing the settings so that passwords and setting including the network names are the same for both wifi networks. I was plagued by disconnections on both networks and even had issues where the hardware would appear to disappear (no hardware installed message). If I disabled one of the networks the issue went away.

Anyway Apple Support asked me to change the name of one of the wifi networks which I did. I was told that having the identical settings would cause some kind of conflict so that if one network dropped, reconnection to either network could fail.

The net result was that I changed the 5ghz network name and since that time I have had no wifi issues with my macs either on Mavericks and now on Yosemite.

I should add that I also run ethernet and wifi on my Mac Pro simultaneously. Anyway, since changing that setting I have also has no issues with the extra (2) being appended to my Mac Pro computer name. This may not be linked but that's what happened.

Sorry if my first comment was not clear, hopefully this one is!

Had WiFi issues with 10.10 (disconnections every 2 minutes), still have them with 10.10.1. So no, it didn't fix them for me. Which is a bummer, since I have to downgrade back to Mavericks again. Mid 2012 15 inch rMBP.

Thanks, Apple

 

[Yaboze]

I have a 2011 MBP and I haven't had any wifi issues. Maybe because it's older and I'm using just "n".

Basically setup everything to do with networks from scratch...

Has anyone tried this? Sounds like a reasonable explanation to me.

For me the 5Ghz band is still dropping off every 15 mins or so, but 2.4Ghz works perfectly. Unclear if it's Yosemite or the overcrowded wifi neighborhood I live in. No BT activated on any device.

It sure is thanks! Unfortunately I can only pick 2.4GHz OR 5GHz on my router.

If I have 5GHz on upto 300Mb/s mode my connection is extremely unstable.
I am currently running a very stable connection to Yosemite on 5GHz with up to 144Mb/s mode.

Unfortunately my girlfriend's laptop can only handle 2.4GHz so she's the one with the ethernet cable!

 

[simonsi]

Bluetooth doesn't transmit on the 5GHz band, only on the 2.4GHz so this pretty much confirms you have BT interfering with your WiFi.

 

[zombiecakes]

My router runs in 5ghz mode only, there is no 2.4ghz being broadcast and I still get dropped when waking from sleep (the 2.4ghz mode if turned on is named something else anyways). Its not a case of networks being named the same, at least its not the only problem.

Update:

For now I managed to at least mitigate the WiFi issues with my rMBP 15'' with discrete graphics late 2013.

I observed a collapse of the transmission rate when bluetooth was switched on and my Apple wireless keyboard and Magic Trackpad connected when booting Yosemite. However, changing (and fixing) the 2.4 GHz channel on an Airport Extreme (old model) to 13 (I tried them all) makes the situation bearable.

The dependency on the chosen channel makes me believe that this is a true rf problem and not solely related to the new Yosemite features.
