I have a Asus WL-500gP v2, flashed to v1.28.9048 MIPSR1-beta18 K26 USB Ext. The external hard drive is mounted on the router /tmp/mnt/sda1. But I can't seem to locate it through window 7. I also like to connect my wireless ready printer to it, but not sure how. Need some help. Thanks
Since your printer is "wireless ready" as you state, you do not need to use the printer capability of tomato which is for a printer connected to the router via USB.
Instead, you need to set up the printer's wireless connection getting it its own ip address. You do this on the printer itself. The only thing you might want to do on the router is to have dhcp give the printer a static ip address so it stays constant.
