i wouldnt know what temp my cpu is I know my router only shows 2.4ghz (57c) and 5ghz (63c) which what they normally are so far it been 2 days since i changes my dhcp lease to 7 days to to match my 7 day reboot cycle, as far as i can tell there isnt any drops happening
Your AC66U has normal temps even on stock cooling. On other hand, AC87 model is notorious with overheating. So, I was wondering if Andyf66's AC87 router instability can be attributed to high temperatures.
My AC87 has lower temps due to active cooling and I did not mingle with DHCP lease time but still it's pretty stable on latest 380.67 firmware.
