Network and USB problems - again...

Hello!

I'm using Raspbian (2014-01-07) on a model B and I'm experiencing the same problems as many other users: network connection is lost as soon as I do anything that creates more network load than "ping". I even can't run "apt-upgrade" without loosing network.

I tried "dwc_otg.speed=1" in cmdline.txt. With this, the Pi's network does indeed run very stable! I haven't had a single loss of connection since I set this parameter, no matter what stress I put on the network.

But, and here comes the well known downside of this solution, it breaks the use of mouse and keyboard!

So, for now, I have the choice between two evils: loosing network nearly as soon as I start to use the network, or not being able to use a keyboard. This situation is very unsatisfying, annoying and frustrating. :(

Apart from tossing the Pi in the trash and buying some other mini computer that will suite my needs: what can I do to have both network and keyboard/mouse?

Would another distribution be a solution? Is this a Raspbian-ony problem?

If you have a digital voltmeter could you measure the voltage at TP1/TP2 - http://elinux.org/R-Pi_Troubleshooting# ... r_problems
If the voltage is too low or varies too much this can cause problems with the LAN and USB devices.
