Hi, I recently purchased the XE-75 PRO to bolster speeds across a 3 story house as reception on the top floor was non existent.

I have tried the X3 units over the WiFi, with the main being directly connected to my router. By the time I receive connection on the top floor, the internet is ok but download speeds go from ~900 download to ~150-300. If I remove the third deco unit and just leave the second my download speeds increase to ~300-500. Is this normal behaviour?

Secondly. If I'm going to hardwire these together. Am I right in thinking the best approach is;

- ISP (Vodafone line)

- connected to my router (do I turn this into modem only mode, I've currently just disabled WiFi?)

- which connects to the main deco unit.

- do I connect a switch to the deco unit, or just connect off the back of the 'main', and repeat?

Thanks any advice is appreciated.
