Go and read the stuff everybody writes around the forum, we may not repeat one and same things just because one will ask dumb questions without ever reading the sticky messages or their titles.
Clues
- to go back from DD-WRT to factory firmware you can only use a webrevert file but not the original one downloaded from tp-link.com. Go read the sticky messages
- to fix the wifi network you may just configure it properly on the wireless tab setting NG-Mixed, channel width 20mhz or 40mhz but not Dynamic mode

Anyone with any ideas as to why would all wireless clients lose network access after 1-2 days of router uptime?
When I boot my WR841N v7, running DD-WRT r18777, all my wireless clients work great for about 1-2 days. After that, they still connect (I can also see them under Wireless Clients in DD-WRT GUI) but they do not get an IP address via DHCP nor do things work using fixed IP. LAN connections are fine and DHCP works ok. If I reboot the WR841N, things will again work for 1-2 days until...
In case it matters, running NG-mixed, CH 11 + lower, 40Mhz.

Looks like that "1-2 days" was a red herring.
Done some testing and it looks like it's related to multicast / IGMP. If anyone starts to watch IPTV, wireless "dies" and will stay dead even after there is no more IPTV traffic.
