@Gaz1 @Chodley the other devices connect to the main router and can see the printer but won't communicate with it. It's like they all have to go through the same point to actually 'speak' with each other 🤷🏻♀️
The Ring doorbell would connect to the router but the signal wasn't very good (even when we had BT FTP with 3 booster discs!). I replaced the battery thinking it was that as it wasn't recharging enough through the trickle charge, but then realised that it was the poor wi-fi signal. I guess it must have been constantly reconnecting and, therefore, draining the battery, which the trickle charge through the electric wiring couldn't recharge fast enough. It's been absolutely fine since installing the TP-Link and keeps itself charged 😃
I told the last Sky engineer that came out that I had sorted it from your solution but wanted to check all was ok as it was. He said, if sorted, don't change it! He was also surprised that the previous engineers didn't offer to hardwire everything. He said they probably didn't want the hassle 😖 It's good to know that they can actually do that and you don't have to do it yourself. Although it would be better hardwired, they would have to do that much drilling inside and we would have a lot of cable on show, so I'll keep that as a backup if this solution doesn't remain stable.
I asked why, when there are a lot of people experiencing similar issues, they don't suggest this type of solution and he said Sky can't promote third party equipment! It's insane as we had problems since we moved to Sky broadband on 6th Dec, have spent hours either on the phone with Sky support or my own time trying to find a solution, had three engineers attend the house, swapped 3 x Sky Q boxes, 3 x routers, 3 x Sky boosters and at least 1 x mini box and all at a time of year when you really don't have the time and really want the Internet working!!! How can this be cost effective to Sky, let alone be good customer service?!? I literally went onto Argos after reading your post with the solution, ordered the extender, collected the next morning and installed and all sorted!
Thanks again so much. I feel stupid that it was such a simple fix and the only reason I didn't look at something like that before, is because I had bought a different brand of extender in the past which didn't make any difference, so I'm really impressed with this little gadget 😃
As @Chodley said, I would like to look at the config to get it all working seamlessly as one mesh (at the moment, according to the Sky engineer, I have two separate meshes somehow working together) so that any mobile devices will just connect to the nearest router/extender rather than all going through the extender, but I'm reluctant to touch it now as it's working. If I brave it any day I will let you know 😂
