Need Advice on Adding a Second Router or Access Point – Using Sagemcom FAST 5364-3.tb and TP-LINK Powerline Adapters

Hey all, hoping someone can help clarify the best setup here.

I’m currently running a home network with a Sagemcom FAST 5364-3.tb router from TalkTalk. It’s doing okay, but I want to improve coverage by setting up a second router (or access point) elsewhere in the house.

A few things about my setup:

* I’ve got several **TP-LINK TL-PA7010 powerline adapters** to get wired Ethernet to different rooms. * I’d like to use one of those powerline adapters to connect a **second router or access point**. * Ideally, I want to extend Wi-Fi coverage seamlessly (same SSID would be nice, I've tried this in the past and wasn't able to get it working properly with an old virgin router 7 years ago)

**Questions:**

* Ideally it would be a cheap-ish router (£50-£100 or so, happy to buy second hand) * Should I be looking for a **router that can be configured as an access point**, or something else entirely? * Any **recommended models** that play nicely with this kind of setup? * Is there a big difference in performance between using a proper AP vs a cheap router in AP mode?

Appreciate any suggestions or feedback from folks who’ve set up something similar!
