I'm working on getting OpenWrt v19.07.3 to run on a Belkin Wemo Insight "smart" power plug (F7C029de) which practically identical to the F7C027 for which an image config exists in mainline. When I run the image I compiled, I'm noticing two problems:
- The RT5350 SoC gets noticeably hotter (~60C) than with stock firmware (~50C). I've read online that this may be the case when the internal LDO (vs. an external one) is used. Here, however, the hardware stays identical so something in the firmware must influence the power dissipation.
- The WiFi is quite sluggish, when transferring files over SSH, I'm getting data rates of only ~160 kB/s. I have no way to assess the transfer rates with stock firmware, but the hardware should be capable of achieving higher rates.
Does anyone have ideas how I can improve on these problems? The WiFi performance is not so critical but the high SoC temperature is a little concerning considering this device will run unattended.
Thank you and best regards,
