I have a G300N wireless router [DD-WRT v24SP2-MULTI (06/03/12) std - (SVN revision 19154)], it appears to be working fine, except for the fact that all of a sudden no new devices can connect wirelessly.
I've check all my setting, rebooted and even added the new devices' mac addresses to the DHCP reservation table. nothing changes. All my old clients can reconnect even after rebooting the router, but no new ones. I've tried with Android and Windows. There's no error message returned, just never connects.
Any ideas?
