Why does the home network not show up sometimes in the network listings

Networkwifi

I'm using a MacBOok Pro, Mac 10.9.5. It happens frequently that when I wake my Mac from hibernation or simply reboot, my home network is not automatically selected in the "Network" section in my System Preferences. When I open the "Network Name:" drop down menu, I don't see it in there either. However, if I click the "Turn Wi-Fi Off" and "Turn Wi-Fi On" one or multiple times, it does eventually appear and eitehr it gets automatically selected or I can select it myself.

My question is, how I can always get it to appear in my network list (assuming I am at home and my router is turned on)? Note I am always within 15 feet of my router (LinkSys E900).

Your 10.9.5 and your Router are having problem of identity.

Your 10.9.5 can not find the correct name, or your router is not broadcasting it correctly.

So try changing the name of your Network, and make sure it is moved to the Top of the Network list and choose different Chanel.

Also you could tell the router that your MAC address belongs to trusted ones.

I would not panic but on they web site they skipped 10.9.5 (Mavericks) and call it Yosemite ?

Probably just a stupid typo :)

The beacon loss event is the key. Your wireless card lost contact with the router and gave up.

If you can, change your beaconing rate on the router to be faster (and slower - sometimes the opposite of the intuitive thing is the answer). Also you should run the Wi-Fi Diagnostics tool which resides in /System/Library/CoreServices and monitor the performance of your setup. This will let you see the signal and noise so you can pick a channel on the router that loses the beacon the least often. There is a lot of data here, but the most important number is the txRate. It is how well your radio can talk to the router radio. All other measures end up reflected here. If you have bad signal, or bad noise, this goes down. The higher you can get the transmit speed, the less likely you will lose the beacon.

It could be just that the Mac hardware doesn't like the beacon pattern of that router and in the end you pick up an Apple router (or another one) - but you should be able to try some more things and perhaps make this better.

Ignore the sandboxing errors - sandboxing would prevent all operation, all the time and not lead to an intermittent failure.

If this is in your home, do you have an older microwave oven nearby? Or a 2.4GHz cordless phone? Baby monitor? Anything else "wireless" (that's not a wireless router/access point)?

Have you tried changing the channel of the wireless on the router? Many newer routers will do a "site survey" and indicate an unused wireless channel.

I have had similar problems with wireless in the past and solved it by changing the wireless channel.
