TomatoUSB

Hi! I recently flashed TomatoUSB on my Asus RT-N16. I have set this router in client mode to connect to the 2wire 3600HG gateway supplied by ATT. I have internet access on both subnets. Additioanlly, I plugged my printer (Samsung CLP-315) to the ASUS router and can print from any device plugged to the ASUS router. However, when I try to print from a device connected to the 2wire gateway, the printing fails.

I installed the printers as shown in the documentation in the tomatoUSB website (on all PCs), I have tried disabling the "Bidirectional copying" feature (router and windows), and I have tried opening the 9100 port on the Asus router from the 2wire gateway setup. I used client mode instead of wireless ethernet bridge mode because I was unable to get wireless ethernet bridge mode to work properly (could not establish internet access). Not sure if this helps but I can remote desktop onto PC1 from PC3 without issues.

Here is a diagram (treat periods as blank space, sorry :/ ):

................................./ ---- PC1 & PC2  (192.168.1.XXX)
................................/
Internet -- 2Wire Gateway------|
...........(192.168.1.254).....\............................../--PC3 (192.168.0.XX)
................................\---- RT-N16 (192.168.0.1)---|
..............................................................\--Printer

To summarize, I would like to be able to print from PCs 1 and 2. Due to the physical layout of my place, I have to have the network set as shown above :/

change your asus to client bridge mode with an ip address that is not in the dhcp range of the 2wire (like maybe 192.168.1.250), and disable nat on the asus. then all devices will be on the same subnet, and all will be able to access the printer

Thanks for the reply ghoffman. Unfortunately I have tried to configure the routers so that they are in the same subnet, but I have no luck in getting internet access on the repeater side. I have tried it with both DD-WRT and TomatoUSB, client mode is the only one that works.

Any additional help is appreciated. Thanks!

Any particular reason you have the 2Wire acting as a router rather than a modem? I would think the simplest solution would be configure the 2Wire so that it just acts as your Cable/DSL modem, and then have the RT-N16 act as the router. Then everything is on the same subnet and going through the RT-N16.

That said, if the config must be as shown in your diagram then double check that you setup the client bridge correctly. The first part of this video tutorial shows how to setup a client bridge in DD-WRT: http://www.youtube.com/watch?v=Ud-Hq3kgvk4 The screens will be different in TomatoUSB (and some of the terms may be as well) but I would think the basic settings should be the same. I used that tutorial to setup DD-WRT on an old Buffalo WHR-G125 for my TiVo to connect wirelessly to my main router (RT-N16) and it works great. (I just setup the client bridge as shown in the tutorial, I didn't continue to setting up the repeater bridge)

Unfortunately I want to use ASUS as a some sort of repeater so I don't have to get wireless adapters for everything past the asus in the diagram (there are additional computers that will be hooked to the asus in the future).

I followed the tutorial in the video you provided (thanks!), but unfortunately had the same results as before (on both tomato and DD-WRT). When in repeater bridge mode (same subnet), I have local network access but no internet access. The curious thing is that I have internet access for about 30 sec and then it drops :/. I have played with all the settings that seem relevant (DHCP disable, DNSMasking, etc) with the same results.

I would like to use tomato, but I might have to buy some USB wireless recievers and a wireless print server adapter instead of the ASUS in bridge mode.

If anyone has any other thoughts please let me know. I appreciate all the suggestions!

It is weird that you can connect to the internet for brief periods and then it fails - I'm not sure what that means. I'm assuming that as you flashed back and forth between TomatoUSB and DD-WRT that you cleared NVRAM using the thorough option and that you are starting from factory defaults.

I'm guessing there is some setting on the 2Wire that is the problem - I just don't know much about those devices. Wish I could be more help.

Can the 2Wire be set as just a modem? You could take it out of the equation completely, put the RT-N16 in there, then get another cheaper router (RT-N12?) to act as a client / repeater bridge.

So a weird update for anyone who might care and anyone who might run into this in the future. I kept trying to access the internet through my Windows 7 laptop, and I kept loosing internet connectivity after 30 secs or so. So tried to plug my Windows XP box and Linux box to the ASUS in repeater bridge mode and I have network and internet access without a problem since…. not sure why my setup is having a hard time handling the Windows 7 laptop and netbook. For now this works well for me, until I update OS on the PCs I guess :P

Any insight into why the difference between the systems? In either case, many thanks to everyone who offered advice :)
