I'm a bit of a novice so any help using a step by step guide would be appreciated. I have been using the latest build (41328) and everything seems to work just fine. I enabled core support and USB printer support. The 2 lights for the 2 USB connections become active. This is as far as I can go. My USB printer is not recognized and I am unable to print. I'm using win10. A prior post makes reference to a fix that I'd like to try.

"What most of us do is make a secure connection to our home network using VPN, via this secure connection you can connect to anything on your network including your USB storage of the router.
This can all be done with DDWRT but requires more setup is perhaps less convenient but you get access to your whole home network and it is more secure."

Does anyone have a step by step way to do this that I can try? Thanks

Thanks for the guide. I enabled SSH but I am stuck on step 3. The rest I am familiar with (the win10 printer install) .
(3) SSH into the router (root and your router admin password), and check to see there is an lpt port available with ls -la /dev/l*
ddwrt-check-lpt-port1
Then check to see that there is something listening on port 9100 with netstat -an
ddwrt-check-lpt-port2

How can I find and access both ls -la /dev/l* and netstat -an? Thanks

I know I might look dumb but when I try to login to the router Putty lets me put in my user name but when I type the password I don't see it appear and I keep getting access denied. What am I doing wrong?

Under Hostname set the IP address of your router
Connection type (just under Hostname): Telnet

Click Open and then the routers console will open:
Username: root (it is always root)
Password: xxxxx (your routers password)

I have the same router R7800 (build 41351) I enabled USB printer support just to try:

root@R7800:~# ls -la /dev/l*

crw-r--r-- 1 root root 180, 2 Oct 21 16:42 /dev/lp2
root@R7800:~#



Quote:
root@R7800:~# netstat -an

There is more but it gives you the idea , the print server is listening on poort 9100

I do not use it, I have networked printers but seems simple enough Wink

I followed all the directions and installed the printer on 2 separate computers. Both show it as the default printer and status ready. When I do a test print the queue says it is printing but nothing happens and then the queue either goes blank or says error printing. Could it be that my router has a physical problem with the USB connectors? Or could there be a bug with the new build I'm using? It was just released 10/15? (41328)
