Hi, I am trying to update my wired and wireless internet connection into a guest room separate from my main house.

With my old set up I had a CAT 8 cable running from my BT Home Hub 6 directly into a 4 port TL-SF1005D switch with my TL-MR3020 portable wireless router and several wired devices connected to it with no problems.

I decided to change my TL-SF1005D to a TL-SG108S Switch so I could have more wired connections with the new switch also allowing up to 1000mbps. However I noticed my BT Home Hub 6 kept crashing due to my TL-MR3020 portable wireless router and this stopped happening once I removed the portable router. The TL-MR3020 is currently set to "AP" at the side, configure guide for each setting is here: https://images-eu.ssl-images-amazon.com/images/I/81mZWT-8RAS.pdf

So do I need to get a more up to date portable wireless router that is compatible with my new switch or am I doing something wrong settings wise?

Thanks
