I'm using a TP-Link AV1000 powerline adapter to extend Wi‑Fi from my house to the garage. It worked well before, but over the past month or two the connection has become unreliable. The garage's electrical power still works normally, including the lights and roller doors, and the adapter itself works all day when plugged in inside the house. What should I check to troubleshoot this? Could the garage be on a separate electrical circuit or have an issue somewhere along the wiring?

First, confirm the exact AV1000 model and whether anything changed when the problem started. Powerline networking can be affected by surge protectors, filters, chargers, appliances, or other electrical noise. The garage may also be supplied by a separate circuit, subpanel, or meter, which can make the signal much weaker or prevent it from crossing between circuits reliably.
Powerline adapters generally work best when both outlets are on the same circuit. A detached garage is often isolated on its own circuit, so the adapter may have worked initially but become unreliable as electrical conditions changed. Try plugging it directly into a wall outlet rather than an extension lead or surge-protected power board, and test different outlets. If the garage is on a separate circuit, powerline may simply not be a dependable solution there.
A wireless bridge or outdoor access point could be more reliable than powerline, but the distance and two thick concrete walls may make ordinary Wi‑Fi difficult. You could test with a directional outdoor bridge or run Ethernet through suitable conduit if that’s practical. Extenders can also struggle with the walls, so placement and line of sight would matter.
The house has very thick concrete walls, and the garage is about 65 metres away, so a normal wireless bridge may struggle. The powerline setup used to work brilliantly, which is why I’m hoping to find what changed before replacing it.
