Wireless woes with new WRT54GL

    I've been running a WRT54G v6 with DD-WRT for the last couple years without any problem. I just picked up a 54GL so I could run Tomato (I need better QOS for VOIP). In DD-WRT I had the TX Power at about 75mW. In Tomato I initially set it to the same and had a really bad fluctuating signal. I've tried everything from 50 to 200 and the higher numbers seem to make it a little worse, if anything.

    I'm on 5 acres and there is absolutely NO interference on any channel. My only other idea at this point is to install the old WRT54G as an AP and use that for my wireless access. I'd like some input from people more knowledgeable than myself before I do that, though. Any ideas?

    I would suggest you try using the ND (New Driver) version over the regular one. I'm not sure this would make any diff on a 54GL, though having new drivers won't hurt.

    I thought the ND version was only for certain Buffalo models. Is that not the case?

    The driver is meant to work better with certain buffalo models, and certain intel wireless clients. It is not specific to buffalo routers, I am actually using it on my own WRT54GL.

    In my experience, I find clean signal strength at 55 mW between my routers... Then again, I am in a city in a completely different environment. Have fun experimenting!

    Depending on your network setup and usage, use Wireless Ethernet Bridge Mode over WDS if it is possible.

    What are your reasons behind that recommendation?

    Okay, I just disabled Wireless on the 54GL and hooked up my old 54G (w/ DD-WRT) as an AP. Everything works beautifully as it did before. So it appears there's a problem with either the 54GL or with Tomato (I'm guessing it's the router). So I guess I'll open up an RMA with NewEgg...

    I was under the impression you were linking both routers together via wifi, please disregard.

    Try ND first

    I would definitely try the ND build before you return the router. I've actually had the best luck using Victek's RAF mods. He uses an even newer wireless driver than the standard Tomato ND build. Try 1.23.8515.5 ND or 1.25.8515.2 ND.

    And erase all nvram and re-configure from scratch to be safe.

    I tried the latest RAF build and noticed a marginal improvement, if any. I went ahead and RMA'd the router and ordered another w/ 2nd day shipping. Here's hoping it was just a bad router...

    How close are your clients to the router? Are you overloading it? The wireless in the WRT54GL overloads and reduces your data throughput if closer than about 2-3m. Is there any particular reason for you to run higher power?

    I have kind of an interesting setup. The router is in my house while we converted our guest house into my office, which relies on a wireless connection. Where I'm sitting is about 20-25m from the router but the house is brick so I drilled through the wall and mounted one of THESE and pointed it at my office. That antenna is connected to the left antenna connection on the router. I kept the right antenna on as it seems to work fine even with the other antenna on the other side of a brick wall. If I'm at work, no one is typically using the wifi in the house. I usually just use it for my iPhone as my personal PC in the house is wired. This is all with a WRT54G v6 running DD-WRT. Been working great for a couple years.

    In the last couple days I replaced the router with a GL, added an Ooma VOIP hub, and a Roku Digital Video Player (Netflix). The Roku was connected via wireless and typically pulls about 2-3Mb/s downstream when in use. It's about 12m from the router with line-of-sight. It occurred to me that running the Roku while using the wireless connection in my office might be part of the problem, but that doesn't seem like too much of a load. I just ran a wire to the Roku while I'm waiting for my replacement WRT54GL so we'll see if that makes a difference (it better... I just spent the last few hours sweating in my miserable attic!! :tongue:)

    A couple other tidbits in case they're helpful:
    AT&T DSL (6M x 768k)
    I use a Cisco VPN client to connect from my office to my company's office
