MacWorld: Wi-Fi issues continue to hamper OS X users despite updates

More Apple Core Rot.

MacWorld reports in Wi-Fi issues continue to hamper OS X users despite updates:

Apple’s efforts this week to remedy the Wi-Fi connectivity issues plaguing many OS X users produced mediocre results, judging by comments left in Apple’s support forum.

Immediately following the Oct. 16 public release of Mac OS X Yosemite, an undetermined but substantial number of users took to discussion forums and social media to report that the OS crippled and in some cases disabled their machine’s Wi-Fi capabilities. As of Thursday, the thread “OSX Yosemite Wifi issues” on Apple’s support forum had 709,855 views and 2,261 comments.

MPG’s view is that OS X Yosemite is the buggiest, most ill-conceived and poorly executed OS release yet. Apple’s fanatical switch to calendar-based releases replete with ill considered if not downright productivity killing “features” instead of quality and reliability driven releases is a fundamental tactical and strategic error.

Apple’s latest Airport Extreme wireless (two of them at home) worked great initially but have been less and less reliable; erratic. I cannot explain it, since they sit where I put them over a year ago. I would like to take them both back and get refund. If Apple quality is so good why isn’t there a 3-year or 5-year warranty and/or “bring it back within a year for a full refund” policy? Stores like REI and The North Face have terrific policies in this regard.

The following window is from NetSpot. A NetSpot representative says that the “100%” figure for noise is something new (a change in behavior) in OS X 10.2.2 Yosemite (these networks are working normally and do not have 100% noise).

After many phone calls to my Internet cable supplier and Apple, due to Wi-Fi stalling out. I had a good call to Apple. They put me on the line with a router expert. After some interrogation, he recommended that I change my channels to 9 and 161.

This has worked for about a month with no problems for Mac Book Pro, two iPhones 5 and 5s, iPad all are running Apple's latest OSX and iOS. My router is Airport Extreme n version, not the newest. My Mac Book Pro is set to run on 5 GHz.

MPG: Thanks to Art for a good tip. For those with time on their hands. In 3 months something might change and then which channels? I wire everything into gigabit ethernet that I can: zero problems and far higher performance.

When I buy an appliance (e.g an Airport), I want to plug it in and have it work at its optimal speeds, figuring it out automatically on its own. I want it to be like a toaster.

Configuring channels with Apple Airport

Charles L writes:

I’ve seen issues where a change in channel fixed the WiFi issue because of interference by other WiFi networks in the neighborhood on the same channel. For example, at my office there are over a dozen visible networks, and a limited number of usable channels. In fact, unless you are at least 3 channels apart, you can experience interference from what I understand.

I also understand that using channel 1, 6 or 11 is preferred, as the intervening channels will be overlapped by adjoining channels.
