I recently acquired two TL-SG108E switches and wanted to implement link aggregation between them. This is because my current configuration uses a single 30m of 36awg flat cable connecting the ground floor router to the top floor server, which limits bandwidth. I planned to extend this with an additional 30m cable and boost performance for simultaneous use of both PCs without significant slowdown. Previously, my setup was: Router → short cable → Ground Floor Switch → 30m flat cable → Top Floor Switch (connected to gaming PC/server).

Now I’m trying to replicate it: Router → thin cat6a cable → TL-SG108E on ground floor → via dual connection using two 30m flat cables for link aggregation → Top Floor Switch (linked to server and gaming PC). My issue is that with the aggregation active, internet access is completely disabled. When I disable one of the aggregation ports, connectivity returns. I’m unsure if I’m setting it up correctly and worry I might have chosen the wrong equipment. Please help me figure this out! Thank you.

I didn't configure any ports on the switch.

You're trying to connect two switches using the two wires and set both ports in LAG mode. However, this setup doesn't support dynamic bandwidth adjustments, which might be why internet connectivity drops. The issue could be related to the switch type—your model is a TL-SG108E (TP-Link), which only supports static lag, not dynamic optimization. Consider using a switch that supports both LAG and dynamic settings for better performance.
