hi, I recently bought an Archer MR500 which was working ok, but dropped out occasionally, plus to get best signal is was in the top of the house, so I bought, what I thought was a good option, a two pack of the Deco M4. The WiFi extension was great, but it keeps on dropping out. So I've disconnected the M4s and moved the Archer MR500 down one floor. It seems more stable but of course the wifi speed is not as good.

im guessing I've bought the wrong product and it should be a range extender instead?

can someone confirm,thanks.
