Q: OSX Yosemite Wifi issues

Still an Amiga 500 and 3000 owner and fan. If I had a network card for my 3000 I'd be using it. As it stands I have a 32 pin to 9 pin serial adapter and serial dial up modem. Okay enough said.

You are correct. In the good ol' days of yore we used the bulletin boards on main frames to download and upload our home made and sometimes college student programs. Students of computer programming wanting to their newly written game out. We would chat via text line to each other FREE! Over, yes the same phone line we made calls to Mommy on. 1200 Baud Rocked! 1900 if you were lucky and caught that modem on a deal. Your computer contained all of your "Personal" data. No Mac Addresses on a PC to broadcast or hack. The only "Virus" was a jerk that handed you a floppy and saying "this is cool, you're gonna love it." World Wide Web was a scam to sponge consumers of their money and all of us Modem people saw the doom when the WWW was announced. Now every PC and Web device has a Mac Address and all personal info is easily shared at the ignorant bliss of all who "love" the internet and portable devices. All this info is floating around as Wi-Fi and Satellite Transponder data being filtered and monitored by the powers that be. Without Hardware and heavy password protection to firewall us, we are at risk of information hijack. Cloud is just a neat place to bundle it up. The powers that be hate the 10,000 or so Amiga 4000 people. Amiga is a renegade on the internet. The old days is when the OS was an OS. The programs unlocked the capabilities of your computer. OS was just the go between. Plug N Play, no drivers! Ah, yes, I remember. End of my memory lane. Macintosh humbled (Apple) computer/Windows/Amiga guy from days of yore.

I don't use Keychain or anything like it. The top secret agent notebook and pen works just fine in recording all my personal data, account ID's and Passwords, Hah! Double secret agent hiding place, also! Cheers!

Sometimes.

Try physically placing your modem and mac against one another and see if your situation improves.

Note, I still can't use bluetooth and wifi together. Apart from that wifi is still fine, not one hiccup.

Not possible for my modern and desktop to be next to each other. Each is in a separate room and can't really move either.

I think you would notice the issue isn't really corrected if you had downloading to do on a regular basis. I can access web pages and such but don't realize my speed is next to nil until I go to download something. I can no longer download multiple files at the same time. I can maybe get one or two small downloads of under 500MB and then need to restart.

Today for an example I had probably 25-30 files on my iMac with a total of around 20GB in total. I had to restart my computer 17 times to get them all downloaded. I was hoping to not have to use my iMac to do this but didn't have a choice.

I have started to send everything to a cheap old Lenovo desktop that probably cost less than 500.00 that is on the same wifi and it has yet to slow down or need to be restarted.

Absolutely stunned to discover Apple's so-called "fix" to Wi-Fi issues in Yosemite (OSX 10.10.2) has actually made the problem worse!!  Seriously, Apple - what on earth are you guys smoking!!??  "The world's most advanced desktop operating system"!!??  Erm, hello trading standards?  This isn't quite accurate if thousands (if not millions!) of people cannot even access the internet because their Wi-Fi connection keeps dropping off.  I have many different devices that use Wi-Fi (from cameras to phones to set-top boxes - many of them considerably cheaper than my 2011 17" MacBook Pro!) and none of them has a single issue with Wi-Fi.  Conversely a laptop that originally cost me over £2,000 is now close to being the most expensive paperweight I've ever owned.  I've owned various Apple products over many years and Apple has always had issues with Wi-Fi - it's as if they've never truly understood the technology.

Wow, they can't fix this issue since Oct. Completely rendered my Macbook pro useless. Non of the solutions worked for long. Wasted so much on it already. The thing just doesn't work. I need to get my work done, and sad to say, it's time to shop for a PC.

Hi again to all new winapple users!

It turns out, this is apple's latest offering to the world. They call it the new apple "nostalgia" where you are taken back to the world of forums and looking for fixes. Market research indicated that most of us really missed the "windows" experience, so they engineered it back into Yoshiteme.

OK, enough kidding. My 15 year old daughter has discovered the best workaround yet. It doesn't last, i.e. you need to repeat it, but it does seem to work (I think!).

step 1: go to your wifi indicator (top right on your screen)

step 2: select any other network you wish, and click

step 3: cancel

step 4: rejoin your own network and "hey presto"

Hope this helps some, if not all of you.

However, as revenge against money grabbing, customer hating, evil apple I would again repeat a simple request to anyone using social media (for personal reasons, I don't, but some of you will, I'm sure). I worked in PR for several years, and if there's one thing large corporations hate, it's negative publicity. If you are affected by this and would like to help, please get the following going:

Good luck fellow victims.

iCloud was a complete mess for me.

Are you running 10.10.2? There was a major improvement in all wireless (WiFi and Bluetooth) handling between 10.10.1 and 10.10.2.

Mark

many people had working WiFi in 10.10.1, and it broke with 10.10.2, for many 10.10.2 just didn't help them at all

Quite

I took advice from my Broadband provider user forum tonight and changed my encapsulation? to LLC  Anybody care to enlighten me as to why this might help? My broadband and wireless both very on/off today Will report tomorrow if this has helped

This shows a legitimate suspicion on the part of your provider toward OSX Yoshite, Paul.

In the seven-layer OSI model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer, which is itself layer 2. The LLC sublayer providesmultiplexing mechanisms that make it possible for several network protocols (IP, IPX, Decnet and Appletalk) to coexist within a multipoint network and to be transported over the same network medium. It can also provide flow control and automatic repeat request (ARQ) error management mechanisms.

Source: http://en.wikipedia.org/wiki/Logical_link_control

Logical Link Control might interfere with Apple Wireless Discovery Link, which is an Apple-implemented custom-ruled protocol, running Multicast.

Address Resolution Protocol has severely changed since Mac OSX Mavericks. Since the partial implementation of Internet Protocol Version 6, the functionality of ARP is provided by the Neighbor Discovery Protocol (NDP). The Mavericks ARP changes may have to do with the implementation of IP v.6.

Source: http://en.wikipedia.org/wiki/Address_Resolution_Protocol

NDP protocol may have its Apple custom sibling in AWLD and not yet be fully functional under IP v.4 instead of IP v.6 capable routers or ISPs, undocumented of course. Whereas most of the internet still (partially) relies on IP v.4.

An illustration of the complexity of this bug. And me being a mere apprentice sorcerer...

Yep, here we may have some trouble cause by the tails: Yosemite may have defaultedly switched to Neighbour Discovery Protocol which is meant for IP v.6 only. Whereas most of the old hardware and ISPs/ part of the internet chain are still IPv.4 only.

That is probably why we got successfull workarounds here stating that killing IP v.6 or switching IP v.6 to "link local" only did the trick for them.

Read this, same source http://en.wikipedia.org/wiki/Neighbor_Discovery_Protocol;

The protocol defines five different ICMPv6 packet types to perform functions for IPv6 similar to the Address Resolution Protocol (ARP) and Internet Control Message Protocol (ICMP) Router Discovery and Router Redirect protocols for IPv4. However, it provides many improvements over its IPv4 counterparts (RFC 4861, section 3.1). For example, it includes Neighbor Unreachability Detection (NUD), thus improving robustness of packet delivery in the presence of failing routers or links, or mobile nodes.

Are we getting somewhere?

As I see it now, it is very difficult to get IP v.4  and IP v.6  router Discovery and Redirect protocols, and respectively their discovery packages NDP for IP v.6  and ARP/ ICMP for IP v.4 to work together under Discoveryd. Would any of you think along, please? i'm just an amateur.

How do you turn off Neighbor Discovery Protocol discretely on Mac gear with only IPv.4 network stuff or ISPs connected?

Thank you!

To check, anyone Terminal prone: run the "ndp --" command (perfectly safe) and post your output.

If the output has chatter, you may have issues.

If "ls ndp" outputs "no such file or directory", you at least have no issues with that. I think.

Good luck!

I'm not sure if its a coincidence, however yesterday i was having a mountain of issues trying to get my MBP Retina 13 to connect to wifi, decided i would make google chrome my default browser and stop using Safari and i haven't had an issue since.

Whenever i start Safari, my connection drops out and I lose wifi connectivity.

Running: Yosemite 10.10.2

Macbook Pro Retina Late 2013

Haven't made any other changes to my system.
