WiFi Issues with MacBook

I haven't had to restart in a couple of days... I'm not saying its fixed, but it sure is a lot better than it was.
Try setting MTU to Manual 1453 (Network, WiFI, Advanced, Hardware)
Configure: Manually
MTU: Custom
1483
May need to mirror on the router depending on the hardware involved
Q-6
Is there any known reason that would help? I work in networking, and am loathe to start playing with MTU on a network without a qualified reason.
Mine seems to be behaving itself the last couple of days. But now I've said that, I'll no doubt start having issues again.
It an old Cisco hack, dating from the dark ages, equal it can and help to reduce drop out`s and has worked for me in the past. Problem is with so much hardware out there that really you need to work out the MTU, by pinging an external external website;
ping -D -s 1500 example.com
If you get the message is too long drop the MTU value after -s, until you get a positive response. There is an overhead of 28 bytes that you need to add to that number. E.g -s 1500 means that the packet size is 1528 bytes.
You can always try on a single system, agree I too would not change an entire networks MTU without good reason and investigation.

I especially don't want to change it on the router, and then potentially have to deal with changing it on every other perfectly function computer connecting to it.
If MTU does fix a problem that exists on only one computer in the house, some other problem is still the root of the issue.
edit: and if it's an MTU problem, there's no good reason that toggling wi-fi off and on would fix it. I appreciate the suggestion, but I'm going to hold off on trying it at least until someone else with the problem says this was a definitive fix for them.
Oh god, I really don't want to have to install WireShark and start troubleshooting this at a packet level...
10.11 is working well for me considering it's a beta. Let us know how it works for you. I was so frustrated with the wifi issue I was willing to try anything.
My problems just started when I updated to 10.10.4. Like others, 10.11 is working without issue. Who would have thought ....a beta may be more stable =/
I tried everything on mine - SMC reset, trashing all the pref files, drinking beer (oh...that was for my sanity!).
But no joy..
!0.11 b3 worked fine, so I knew the hardware was ok.
I changed the MTU to 1300 and that fixed the issue. Setting the MTU back to automatic (i.e. 1500) seems to be OK now, the link is stable and pinging my router all the response times are around a few ms rather than being all over the place.
Hope that helps some people...

Now running the public beta of El Capitan, and seeing solid wi-fi performance so far. We'll see if this continues.
I have *not* adjusted MTU.
A personal theory: it's possible that the networking changes in 10.10.4 were the big fix for wi-fi, but it took doing a more thurough OS upgrade to a new major version to wipe out some of the bad settings and profile bits. Pure speculation, though.
I've been plagued by wifi problems from Day One with this rMB. I have 10 other Apple devices in the household (iPads, iPhones, Apple TV, MBP, two MB Airs, etc.) and the 12" rMB is the only device having issues. I've tried everything possible and it still requires switching wifi off and then on maybe 20 times a day. I love this computer but it's just killing me.
I downloaded 10.10.5 a couple days ago and POOF! Completely gone. Not a single dropout in 48 hours now.
Go figure.

I downloaded 10.10.5 also but it made no difference on my MacBook retina. It drops the internet connection after waking from sleep almost every time. I have tried everything at this point. Reluctantly I shall probably return it since I am still just within my 14 day return window. It's ironic that the Macbook that Apple is touting as a wireless only machine, has broken wifi for many people. My retina MacBook Pro, iPad Air and iPhone have no problems on the same wifi network. Even the genius at my local apple store where i took my retina MacBook in to be fixed told me there was nothing he could do and confessed he was having exactly the same issues with his own MacBook he had just purchased! He said he thought it may have something to do with new antennas Apple is using since the issue seems to be happening mainly to the latest models of MacBooks, iMacs and MacBook Pros.
Three more days of testing down, and I've been playing music over Airplay a lot to be sure I'd notice wi-fi drops. Everything has completely stabilized, no wi-fi drops since going to 10.11 public beta 2.
There is a wifi issue on my base 1.1 I notice every now and then where if i close the lid and put it to sleep, upon waking (say 15 mins later..), even though it appears to still be connected to the network, I don't have access to the interwebs until i turn wifi off and back on.
I'm assuming that's just a bug that will be resolved with an update?

I wouldn't 'assume' anything. Until it's fixed it's a disaster, that's all.
(same issue here, BTW)
They are taking way too long to fix this.

You could say so. My issue, at least, is not limited to MacBook. It has been there since Mavericks on MBA. Actually, the very last update in Mavericks fixed it, and then Yosemite broke it.
