Bluetooth + Wifi Interference issues

Hi, I recently bought a Magic Mouse for my MacBook Air. My wifi connection worked fine before (I had the Bluetooth turned off, no bluetooth devices at all), but after I started using the bluetooth for the mouse, the wifi connection is almost unusable. Sometimes is better and I don't have interferences at all, sometimes is worse - but most of the time is very slow. Changing the wifi channel sometimes works, but only as a temporary solution. Turning off the bluetooth restores the connection to the normal speed.
Anyone with the same problem? Any solution for this, besides stop using bluetooth?

MacBook Air (Late 2010), Mac OS X (10.6.6), 13", 128GB storage, 4GB RAM

Try restarting your router so it can choose the channel with the least interference. If you have 5Ghz capability that would be ideal.

Here are other things that affect it, maybe something will "ring a bell".

Same problem here. In my case, the Wifi doesn't auto connect when I'm NOT in my office, where I have my bluetooth accesories (keyboard and magic trackpad).



My guess is that the interference is produced when the bluetooth keeps looking for known devices to pair with. I have reassured this since if I turn off the bluetooth, all the Wifi problems disappear. Actually, this is my current solution to the problem.



This could also explain why there aren't too many users complaining about this, since it only happens to people who use bluetooth devices regularly.

Had the same issue here, here is how I resolved it:

You have to define a new "Network Location" and set proper network service order in Preferences.


First you need to be logged as an administrator on your system (if you're the only user, that should be the default)


Open System Preferences

Goto Network Pane

On top of that pane is "Location" that by default is set to "Automatic"

Click on the right of that selection and then "Edit Locations"

Click the "+" to add a new location

Use any name that makes sense for you then "Done"


Select the right WiFi network (in Network Name) just below Location on the preferences pane


Then at the bottom left of the pane, click on the action cog (gear icon just above the lock icon)

Select "Set Service Order"

Then make sure your WiFi network is above Bluetooth.


Cheers!

TEMPORARY...

I tried changing the WiFi Channel, and it seemed to fix the problem. Then it came back.


Why did the problem come back. I don't know for sure, but here's what I suspect:

After I abandoned the interfering WiFi Channel, so other device with automatic channel selection (maybe in my home, maybe in a neighbor's home) saw the empty channel space, and jumped on that channel.

This might explain why the FIX is only temporary.


I wonder why the mouse/keyboard can't just use the wireless network. Latency?

My roomate and I were having the same problem. I have the new Retinal Display macbook and recently purchased the bluetooh enable magic mouse and with it on our internet was practically not working.


After some quick googling, it seems changing the your wireless router settings seems to work. Cisco suggest channels 1,6,11 or three steps in either direction from your current settings. And VOILA we have the internets.


Some other solutions suggested moving the router away from the conflicting devices. That didn't work in our case, but we have a pretty small apartment space.


Good luck.

I work in the IT department of a school district, and this year we have purchased about 300 macbook airs. We sent a few COWs of them (Cart on Wheels, ~30 machines per cart) out earlier this school year with no issues.


We've begun replacing aging staff laptops at our two largest highschools; one school is split between Mac and PC, the other is almost entirely Mac. We did the first school, the Mac/PC split, with about 35 airs. No problems.


This last week we went to the almost all Mac school, with ~80 airs, and network connectivity steadily tanked the more airs we installed. We were able to determine there was a large amount of intermittent packet loss at the 2.4 ghz band, but no issues at all on the 5 ghz band. This was effecting PCs and Macs, including older Macbooks (not airs, circa 2007-2008). The problems died down once students and teachers left the school for the day.


We could think of nothing at all different from the rest of the school year, save the installation of a bunch of airs. After reading this thread, I've used Workgroup Manager to disable Bluetooth on all of the staff airs we installed. I'll know if this worked come Monday, and I'll respond in this thread with the results.

I've had the same connections issues on my macbook air, I found the solution on another post and thought I would share on this post.


The problem apparently is when a system is upgraded ie. Lion to Mountain Lion, something from the old system preferences messes up the new system preferences, specifically network settings.


So the solution what worked for me is to naviagate to:


Library/Preferences/System Configuration


Once you find the system configuration folder delete it, wala your bluetooth and wifi will work again!

Disabling Bluetooth did nothing for us. We are going to try out the suggestion from Haida12, but currently teachers are on summer break so they check their laptops out during the summer. Additionally, two things have come up. A recent Apple patch specifically deals with wifi issues, which might resolve this. Also, our wireless manufacturuer, Aruba, came out with an update to their controller that includes better support for Macbook Airs.


I will come back to this post later this fall when things have settled down and we've had a chance to evaluate things, and let you all know if we had any luck. We've got another 300-400 macbook airs to order and ship out to staff before December so hopefully we are able to get this resolved!
