I have temporarily moved into a rented apartment for 4 months, which has wireless. The trouble I am having is that the access points here are wifi only and no RJ45 and I need to use RJ45 to connect some equipment that I am working with. I have purchased an RT-N66U and installed Tomato (shibby ver. 1.28) and successfully replaced the existing access point, but now I want to enable the access point that I have replaced as it links wirelessly to 3 others. Can I plug in a cable from the access point to my RT-N66U and get it to access the internet via my router?

I have no access to the existing wireless access point, and don't want to reset it as it's not mine. There is another router situated in the roof somewhere which I also have no access to, but it's supplying my RT-N66U internet and I most definitely have a double-nat, which although isn't the best way of doing things I am limited with what I can do.

Any suggestions on routing tables, vlans etc would be helpful, but I have no experience in these fields before - but I know the tomato firmware can cater for this.

My router is set to IP and dhcp is The wireless access point address was but this was assigned by the router in the roof which has the address There is a cable from this router going to a wall socket which I now have my RT-N66u attached to via the WAN port.

I understand it's scruffy and it isn't the way to do things but I have tried to ask for the admin details but as the wireless network is looked after by a third party and nobody knows their details I am stuck with this dilemma.

Network diagram here network

  • The post is somewhat contradictory. To clear it up, best to add a schematic showing both your current and requested network architectures and IPs, and which router you can admin.

  • Apologies - I will do a diagram. Jun 30, 2013 at 10:19
  • The architecture is becoming clearer, but still some gray spots: Does the diagram show the actual situation or the one you want to achieve? Do AP1-2-3 function currently with B or still connect to A (if yes why change)? How can we know whether AP1 can connect via a cable if we don't know its make? Does AP1 connect to AP2-3 or do they also need cables? Is AP1 the one that you replaced?

  • i need to change as the network that this place has come with is wirless only - I need rj45 for a small network I run. - the picture is how it is at the moment, with the dotted line between a and ap1 being how the network was without the kit added. Jun 30, 2013 at 23:52
  • If AP1 is already connected via a cable, what exactly are you trying to achieve? Might be a good idea to post the diagram of the network as you would like it to function and to highlight the problem-point.

Ended up resetting the AP's (ubiquiti air-fi) as a third party has access to everything they do and that isn't something that I want to happen. Have taken that up with the rental agent and have permission.


Fixed as they were ubiquiti aifi AP's and I don't want any third party unknown to me to have full control over my wireless network. I reset all AP's to my own network.


An access point does not usually allow for another RJ45 ethernet connection. It takes one connection in and then it's wireless only from there on out. With that being said though, if you have the information from the network then you can create a wireless bridge.

My home network has our main router attached to the Xbox and a bridged Linksys E2500 that has DD-WRT (I know you have tomato, but same concept) so I can plug in my desktop with RJ-45. So my main router is set to and my bridge is set to Mask and Gateway are all the same, and there were a few settings I had to tweak.

I found an article that may help you turn the router that's been modified into a Wireless Client.

  • I can't use a wireless bridge as mentioned, the wireless encryption is TKIP not AES. Jul 1, 2013 at 7:03
  • I did some reading and found that Tomato does have an issue with TKIP. That was not mentioned so I couldn't have known that anyways. If you're stuck with Tomato then good luck, but if you switched to DD-WRT you may have better luck. I've used DD-WRT as a bridge and wireless client.

  • DD-WRT although good, is nowhere near as solid as tomato. DD-WRT makes great wireless bridges, which tomato doesn't though. Jul 1, 2013 at 19:23
