RE450 transmit vs receive speed
I just received my RE450 range extender yesterday. Updated it to the latest firmware (20171215-rel55534). I set it up in the livingroom going through a few walls about 30 feet away from the main router which is an Archer C1200, I know which is technically slower than the RE450 AC1750. I'm using an extension cord to raise it a little higher from the lower outlet.
I turned off the extended network since I'm only using the RE450 as a wireless bridge to LAN to the livingroom. I'm using the 5GHz channel for the bridge, and my channel is clear viewed using a WiFi Analyzer app. I have a LAN computer on each side of the bridge. I run iperf3 with 10 parallel tests to maximize my bandwidth and I measured the RE450 transmit 336Mbit and receive 526Mbit from my C1200. I would have thought the numbers would be reversed due to AC1750 vs AC1200.
I haven't tried all possible tests yet, like swapping the computers to see if it's computer hardware/driver related since that would be difficult. But accessing a 2nd computer in the livingroom had the same result. Has anyone ran into situations like this when each direction has a different speed? Could it be the lack of beamforming in the RE450?
Attached a screen shot.
