Hi, I am currently having an issue with the wifi on my new 2017 model, non touchbar 13 inch macbook pro. My setup is the following: Archer C7 router with the OpenWRT firmware installed Macbook pro 13" 2017, non touch bar model with latest High Sierra installed and updated Lenovo Carbon X1 3rd revision, 2015 model MyCloud NAS, attached to Archer C7 via gigabit ethernet cable. Both macbook and lenovo are on the same table, approx 3-4 meters away from the router. Both connected to the 5Ghz ac wifi, both on channel 36, 80Mhz. My issue is that the speed on the macbook is always noticeably slower than on the lenovo, despit they are next to each other. Example: running speedtest on lenovo gives out 95-100mbit (my connection is 100mbit), running speedtest on the same server on macbook pro gives 40-70mbit. Downloading a file from NAS on a lenovo machine gives out about 35-40 Mb per second, the same procedure on macbook reacher 15-18 Mb per second. It looks like it's not a router configuration issue, since the macbook always performs slower, and it never showed me 90-100mbit on the speedtest while lenovo always shows these numbers. Knowing that there could be at least 15-18mb (as per LAN transfer from NAS) between the macbook and the router, it looks very very strange that it's not possible to get the max speed from speedtest. I would appreciate any info re this issue as this is just driving me crazy! Thanks. P.S.: It is not a openwrt firmware issue as behaviour was exactly the same on the stock firmware P.S.2: I have also tried everything from this thread with no success.
