Changed the wifi channel to 1, and no problem what so ever, no matter the resolution of the screen. Don't know if it works with the lid closed.

So changing channels is a solution, now if we could only figure out why the heck that was happening haha. Then we'd be doing Apples job.

I'm trying to use mine in a enterprise environment so changing the channel on the access point is not that easy. I just broke down and bought the USB to ethernet since I have drops at my desk. Obviously works like a champ now.

I changed my channel on my router this evening and will report back if I have any issues.
I am willing to try anything at this point.

So far so good!
Changed my router channel to 1 a few days ago and haven't had any issues since!
Not the best situation for people in enterprise environments but it seems to be a solution for me at this point.

Channel 1 is the answer to my problems it seems.
10 days in and I haven't had an issue since, lid open or closed.

Same problem. My setup:
- MacBook Pro Retina
- Mountain Lion
- External monitor attached via Apple Thunderbolt-to-DVI adapter
- Network connectivity available via wi-fi only
Consistently, I could not connect to wi-fi with the Thunderbolt cable attached but could with it detached. I changed the wi-fi settings on my Linksys router to use channel 1 instead of channel 6 and the problem disappeared.
Thanks to all of you who posted before me and helped me solve the problem quickly!

- Macbook Air late 2010
- new LG 27" HDMI Monitor
- third party hdmi adapter
Instant drop from 50Mbit to 2Mbit when connected, physical proximity is NOT important. Macbook can be right next to monitor (connected to Windows PC) and still achieve 50Mbit, only when it it CONNECTED the speed drop occurs.
Tried swichting channels, doesn't work for me (best I can do on other channcels is 5-8Mbit).
- Swiching to 5Ghz! Works like a charm. (but not good for me since my external WiFi USB Stick on my PC does not support 5Ghz)
- Connecting to Monitor (if possible) via VGA. Worse display quality but full 50Mbit.
This gets more and more confusing! -.-

I had same issue connecting Early 2011 MBP via off-brand mini-displayport -> HDMI -> DVI on an older model Samsung LCD.
It was working fine, then I was playing with Mac Settings for the Display Resolution. Changed from 'best for display' to 'scaled' and my network dropped off. Changed back to 'best for display' and still didn't come back. But then changed from 75 hertz to 60 hertz and instantly my wifi network works again!
Hope this helps someone else out there...

ready for some real Voodoo?
It seems that changing the display preferences is critical
I have had this set up:
2012 MBA -> Generic Thunberbolt to DVI Adapter -> Apple Cinema Display 23" from 2005
Wireless has been working flawlessly on Channel 11 for weeks, with the lid closed.
A friend came over with his 2012 MBA and I said "hey, take a look at how it looks on a bigger screen"
We plugged it in, had to open display preferences on HIS machine and do arrangement and the like. Didn't actually use the net.
Later that day I plugged in my MBA and .... slow to no wirless.
Wondered about new interference, put in an old Airport Express to boost the signal.
Have now changed the channel to 5 and am getting about 10Mbps

I'm one more user experiencing this problem, which was largely solved by switching my router to channel 1.
I've got a mid-2012 MacBook Air with great wifi speeds (50/25 Verizon service testing at those speeds or better) until I plug in my Dell 2007FP 23" monitor through a Apple Thunderbolt to DVI connector. It then drops to 10-20% of those speeds, especially the download rate. Changing the Dell monitor resolution also largely fixes the problem.
BTW even after fixing the problem by using channel 1, when the MB Air lid is open the speeds are 20% higher. Turning off bluetooth also speeds things up incrementally.
Thanks for everyone's posts.
