recently I bought new TP-Link Archer C7 V5 WiFi (EU) router. I would like use DD-WRT on it, but I have problem with DD-WRT firmware.
First I tried upload 47528 version via stock web interace but I got an error: "Invalid file type". So therefore I used TFTP method (192.168.0.66/ArcherC7v5_tp_recovery.bin) and flash passed, but DD-WRT web interface is "broken". When I connect to 126.96.36.199 I see only bare HTML without CSS/JS files. You can see "homepage" at https://i.ibb.co/vhf4CNY/DD-WRT.png
I tried same version second time (before it I flashed router back to the stock FW), I also tried 44715 version and with the same result.
I already used "factory-to-ddwrt.bin" file. BTW I used OpenWRT firmware on this C7V5 router without problem (I was not able to configure it as Wireless Bridge mode).
When I opened 192.168.1.1 using Firefox it display correctly! So I run Chromium in Private Mode and it works too :-O But when I open in normal mode, than not! Even when all plugins (uBlock Origin) were disabled. I am deeply surprised.
BTW I used DD-WRT v3.0-r47495 (09/28/21) using web flash method.
So, it was just a browser or cache issue as far as the DD-WRT webUI being broken. You were probably also on the same browser you were cruising the Internet with. Happy DD-WRT'ing.
Yes it was browser/cache issue. But I did refresh page using F5, Ctrl+F5, Ctrl+R, Ctrl+Shift+F5, Ctrl+Shift+R, even I opened source page using Ctrl+U and in source window I clicked on css and js links. Result always was 404 - not found. Therefore I thought that problem is another else. Now Chromium can show DD-WRT pages without problem.
