Macbook Pro internest slows down with external monitor

[guidoverduci]

Hi-

I have a 2011 MBP on my desk upstairs, while my router is downstairs. I noticed that the internet speed, via speedtest, is much slower upstairs but I figured that was because of the distance from the router. Today I did a speed test both upstairs and downstairs where the laptop sits and it's virtually the same speed. However, when I plug in my external monitor the speed drops from 25Mbps to 6 Mbps. Any ideas? Thanks.

ive seen this before, where people say clamshell mode causes a slow down in network speed

So.. Is it something I just have to accept?

seems like an unsolved conspiracy. I have not noticed this however. I assume you are using clamshell mode? if so, try it with the mbp opened and your monitor as the secondary. did you already try all those type or scenarios?

yeah, tried all that. What a bummer. I liked having it in clamshell mode, but it looks like I'll have to find an alternative.

Sorry to bring back the old thread, just thought it could be helpful for someone. I hope you found a solution for this, if not it's because of the router and the dvi cable, that is causing interference for the signal.

Two ways to fix:
- Change the channel in your router (manually) if you know how to do it

Else
- with your monitor connect to mbp, restart the router it might automatically pick up a better channel.

Else call your internet service provider to help with changing the channel.
