Problem with homeplugs

[neonplanet40]

Equipment:

BT Home hub 5
Bt home plugs
TP-LINK av500 2 port

So I have been using the hh5 and bt home plugs for a while with no issues. However, I needed a wired link from my server to my htpc. I tried wireless but it was awful. Couldn't even stream a movie.

However since I added the new TP-LINK devices the home hub keeps crashing. I originally had both the TP-LINK and the bt plug directly attached to the back of the home hub with a cable.
However I have now tried juat one lead going to the back of my router which is connected to my switch. I have tried connecting both home plugs now to the switch but it still isn't working.

If I take away the TP-LINK it works fine.

Now I know the problem is with the TP-LINK and the fact my home hub seems to hate a major networking brand. but any idea what is causing it and if it can be fixed?

It would be astonishing if you could use two brands of home plugs on the same mains circuits. Each uses a slightly different approach and will interfere with the other. You might try again with wireless if you bought a higher powered access point.
