Calling all wifi networks

Ok, complicated situation so here is my summation of my situation. My DSL modem is in my office on the north side of my house hooked up to a D-link N router (I have it set to "G only" mode). One room over is my living room and kitchen where I have a wifi camera, my TV computer and my xbox 360. One more room over is the master bedroom where I have a B/G linksys DDWRT router that picks up the D-link SSID and then rebroadcasts it out to the backyard and it sits next to a big window. Out in the backyard I have a home office and that is what is giving me problems.

I am having marginal results using my main d-link and then the bedroom and another dd-wrt out in the shed to act as repeaters. This works....most of the time and if I am REALLY lucky I might be able to watch regular definition video files without lag or jumping.

So I splurged and bought a dual band linksys router and PCI card for the home office. My idea was to made the duel band like a "backbone", bring it in to one PC in the home office and then share it through the ethernet port to the rest of the PCs. Thus far I have not been able to even see the 5 ghz network and only get like 2 bars on the 2.4 ghz band (set to N only) in the office.

A few questions, is it best to leave the setting on "N only" or leave them on "auto"? Any thoughts on the network in general? I was trying to split it up as much as possible to isolate traffic.

 

I take it therefore that the home office has working power sockets.

In which case homeplugs are the way to go. Example below but other makes available.

You will of course need to purchase at least 2 units. I personally have the one above PL-85PE and a PL-85PEW which is the one that has an ethernet port and wireless connectivity also.

The only proviso I would add is that the 1st unit that plugs into your router will have no issues. The other homeplug [say in your office] may need to be connected to a switch rather than directly into your pc.

Lastly, wired homeplugs are transparent to router so they have no IP address and you can change the default encryption too.

Good Luck
