Router Model: TP-Link Archer C7 AC1750 V3.0 (2.0 firmware interchangeable)
OS: Ubuntu 18.04 LTS
Original goal: Get OpenWRT with automatic reboots, ad blocking hosts file, and hardware NAT acceleration, without causing high CPU usage on laptop.
Originally loaded DD-WRT on router but WLAN disappeared when security key set. Decided to switch to OpenWRT by reverting to stock firmware, using 'ArcherC7v2_webrevert.rar' :
Then I upgraded to this LEDE optimized custom build for Archer:
It worked, but my CPU temp spiked to 60C every time I visited a heavy page like YouTube
I wanted to revert to stock firmware, then flash stable 18.06 release from main page.
Unknowingly I used the same Webrevert file from above (may have been configured for DD-WRT) over SSH to flash.
After 10 minutes, it didn't reboot, so I unplugged my router and replugged it--then navigated to 192.168.0.1--and nothing. Same for 192.168.1.1
Back USB LED Lights on constantly.
- All front lights go on.
- Only power, 5GHz, and 8-pointed star(DMZ?) on,
- All except 2.4GHz and rightmost refresh(?) light up
- Finally just power, 5Ghz, and 8pt star on.
All happens in less than a second each, in 4 seconds.
Therefore, I cannot access failsafe mode.(blinking star never occurs) Pressing the WPS/reset button does not affect anything. Nor 30-30-30 reset. Unable to ping 192.168.0.66, 192.168.1.66 or 192.168.1.1 or 192.168.0.1
I set my IP address to 192.168.0.66 and attempted to TFTP (via ethernet LAN):
Stripped Version (did not rename) -
Original firmware (renaming it ArcherC7_v2_tp_recovery.bin):
Both said successfully uploaded on TFTP, but I'm convinced that I am just using TFTP to transfer it back to myself. The router doesn't reboot after 10 minutes or more, I can ping if my wired connection is set to 192.168.0.66, but not otherwise, and accessing to 192.168.0.66 brings up "Not Found" in browser.
After recently purchasing this router, I am REALLY hesitant to use a serial cable and don't have any soldering equipment. I do have another PC to test TFTP again on.
If you recognize this problem, or boot pattern, please share, it is highly appreciated. Thanks...
