How do I get this PC on my LAN?

[GetOffMyLAN]

I have 2 routers. One of which was provided by my ISP and essentially just sits in the living room as a modem in bridge mode. My other is an aftermarket router which has been flashed with DD-WRT, Linksys EA6500v1, if that's of any relevance.

I have a 50ft Ethernet cord running through the wall outlets into my room, powering my DD-WRT router's WAN port to create an unrestricted, full speed PPPoE connection of its own. This router is used for all Wi-Fi devices and nearby Ethernet devices, essentially acting as a primary Gateway router.

However, I have a desktop computer located in the living room where the ISP router is, and the only way it can get an internet connection is by hooking it up to the ISP router via Ethernet, also establishing PPPoE. As you can imagine, this creates various problems. I'd like to avoid having to buy a Wi-Fi card for it, as the wireless connection gets heavily degraded in that particular room.

What adjustments must be done to both routers that would allow me to somehow have this desktop computer hop over from the ISP router to my DD-WRT one? Perhaps I should look into LAN-to-LAN?

The firmware of my ISP router is highly limited, meaning that I have little options to do things such as create static routes on it.

I'm already anticipating that I'll have to reclarify my issue many times as/if this thread moves forward. Thank you so much for taking the time to read this and maybe even replying with your two cents.

Not easy. You would need to route the connection from your desktop PC, to the Linksys router. The connection between the Linksys router's WAN port, and your ISP's router in bridge mode, would have to stay.

I would say, move the Linksys router, which seems to be doing your primary routing duties, into the room and next to the ISP router in bridge mode, and then get another router, set it up as an Access Point only, and attach it to the 50ft ethernet cable.

Just deploy another length of cable next to the first one and connect said computer to your Linksys.

Just move the DDWRT router into the room with the bridged router.

Then you can plug a cable from the DDWRT LAN port to the wall, and then in the room (where the DDWRT used to be) plug a cable in for access. You can even put a switch in that room to add extra ports, or another WAP.

Looks like you guys already covered it though lol.

Who is your ISP and what type of internet connection do you have? If it something like GPON you can take the ISP supplied "modem" out of the equation. if it's regular DSL or something then never mind.
