Hi everyone, This is definitely a laptop issue as I’ve tested different laptops against my WiFi at home, restarted the router, tried different locations, and still it’s just my laptop with this problem. The tx rate is low. Right now, it’s at 1. The WiFi router is literally just the room next to me! The highest it’s been is around 80 tx rate. This became an issue probably around March this year, it was never like this before. It also has issues sometimes connecting to my phone hotspot so there is an issue but I’m not sure what steps to take first! Do I need to repair anything inside? What can you recommend please! Thank you!
The first thing I would do is alter your WiFi AP names for each band as an example ACME-2_4ACME-5_0 So you can distinguish which band your system is connecting over. When you have a single name ACME there is no way to know! This is important as you’ll want to flush out your network cache. Open up your Network control panel and click on the Advanced… Button to open up settings window you’ll want to delete the preferred Networks and do make sure you note the passwords before you delete them so you can add it back. Here’s a useful tool WiFi Exporer so you can see your connections. Next I would inspect the antennas exiting the hinge area as sometimes they get damaged if not properly seated. Follow this guide MacBook Pro 15" Unibody Mid 2012 AirPort/Bluetooth Board Replacement to Step 10 so you can get under the board to inspect the cables entering the hinge if the wires look damaged you’ll need a nw antenna unit.
