Ask Slashdot: DD-WRT Upgrade To 802.11n? 196

First time accepted submitter krinderlin writes "My home network consists of a Linksys WRT54GL for WAN access and a WRT54G version 8 for a wireless bridge for my Blu-Ray and old XBox 360*.

    Quite a powerful router, I use it heavily for my VPN. It also allows you to upgrade to DD-WRT right through their interface.

      It should be noted right away that the RT-N16 is only a single-band router, which could be make or break for many people. I use one, the thing is designed for custom firmware. But if you have to use the stock firmware for more than an hour, submitter would go insane.
    • I have one using Tomato, and I love it. I was a huge fan of DD-WRT, but the simplicity of Tomato won me over. It has plenty of power for me, and the UI is pretty. It handles torrents very well since it's pretty well loaded with RAM.

      Having N at only 150mbps wasn't a dealbreaker for me. Wireless is just more reliable with multiple antennae.

        Wireless is just more reliable with multiple antennae.

        Indeed, I noticed that my old two-antennae router had trouble reaching my dungeon downstairs. The undeclared members of my family could only get intermittent reception. Now they can access youtube and email from this remote part of the house and I don't get so many complaints.

    • Agreed. I've had my RT-N16 for about a year. It is great with DD-WRT (I guess it supports Tomato, but I haven't had a need to upgrade). I did have problems with mine overheating (not overclocked or anything), but some left over heatsink coolers from way-back and an ancient graphics-card cooling fan completely fixed the issue for me.

      The RT-N16 seems to have some quality control issues, but for the price, there was nothing better when I bought mine. There may be better options now though.

    • I too have had great experience with the N16 running Tomato USB. I convinced a couple friends to get it as well, and they're also very happy. The router has tons of RAM, ROM, and CPU. My only complaint is that it's only 2.4GHz, not 5GHz dual-band. However, the only 5GHz device I've got is my work laptop, and I have a separate AP for 802.11g and not much else around me, so 5GHz isn't that big a deal right now.

      There are a few advanced features of DD-WRT that Tomato USB doesn't do (at least from the GUI),

    • RT-N16 all the way. I have plaster walls in my house (the kind held up by perforated metal sheets which make excellent faraday cages) and couldn't get wireless through. Got this router specifically because it had 3 removable antennae. Threw on some monster 12db antennae, loaded DD-WRT, tweaked a few settings and poof I had wireless through the whole house. The antennae I got had super long cables on them so it made finding the perfect placement easy.

    This router is an absolut beast in terms of range and throughput. The DD-WRT support is terrific and the device is rather cheap.

    The Netgear WNDR-3700v2 is powerful, reasonably cheap, and well-supported. It also is the target of the CeroWRT project, which deals with bufferbloat, and should be of interest to advanced users at this point. Bufferbloat changes are also being adopted into stock OpenWRT and the Linux kernel, so eventually will make it to more routers.
    • I mostly agree, except I found it to have infuriating reliability issues compared to my old router, a WRT-310N. Every so often - say, once or twice a day - it'd just stop passing traffic to/from the WAN for a minute or two. No rhyme nor reason, no useful info in the control panel or logs; the traffic just went into a black hole. My 310N never, ever did this.

      I eventually wound up running (and am still running) a dumb-but-works combination of the WNDR-3700v2, using its native firmware, acting purely as a wire

      • Try OpenWRT. It might have some bug fixes missing from DD-WRT. It has the advantage of being fully Open Source, while DD-WRT wants you to pay for some features and some platforms. The development version runs well and is updated continuously. It has so many packages that it looks like a desktop/server Linux distribution. It seems to be directed at a more advanced user.

        HomePlug is usable, but it's comparatively underpowered. Good wireless speeds are now 300-450 mbps.

      • I tried homeplug for a while. It was nice and fast, compared to 2.4GHz wireless at least, but it corrupted data: about half of my large file downloads wound up corrupted. I'd download a 4GB ISO and find it didn't match the sha256sum, re-download it and it'd be okay.

        Never happened on the same systems since I ditched the homeplug and just ran an ethernet cable across the ceiling to the router, so it was definitely the homeplug screwing it up. Mine are now collecting dust...

      • It's really hit or miss. I find that when I have two homeplug endpoints on the same breaker circuit, I can get a solid 100mbps. On different circuits, I get 1-2mbps. Homeplug just varies too much between manufacturers and home wiring. If you find a homeplug product that works for you, go for it. Just don't expect it to be the best solution 100% of the time.
        • If the homeplug nodes are on opposite sides of the breaker box your signal goes through the transformer on the pole down the street.

          • ps - I use homeplug *and* WDS at the house - mainly because there are three walls and a floor between my home router and the rack where directv/PS3/xbox lives. There is a WDS node in the kitchen one floor below the my router and another one in my bedroom feeding a directv receiver. This is a fairly new house and the spousal unit won't allow me to pull wire through her walls.

      Maybe because that list is full of routers that are old and not currently available from places like Best Buy and Newegg. Knowing that DD-WRT works great on a router that I cannot actually buy is pretty useless. Also, many routers have multiple versions, and DD-WRT only works on some of them. Yes, that list would have what you need, but the work needed to go though the list to find something easily available would be a LOT of work.

    I've ended up replacing most of my previous kit with acquired-from-eBay Apple kit. 802.11n over 5Ghz for some devices, and over 2.4Ghz for others, with fallback to 802.11g for older devices. Airport Extreme for the main routing, with some Airport Express units for the music system. I used one as a wireless bridge for the PS3 for a while, but, since switching to an old Apple TV for playback, everything's streamed fine over Wi-Fi.

I use the wireless only to hook laptops and cell phones.

      It depends a lot on the wiring in the house, so the system is sensitive in that way. The wiring in my house is good, though.

    DD-WRT development is basically dead. There hasn't been an update on their homepage in over a year.

    There are unofficial builds in the forums, but even those are at this point old. For example, the "Recommended" version for Broadcom-based devices still includes an ANCIENT release of inadyn that doesn't work with most dynamic DNS providers at this point (nearly all implemented SSL security which breaks with older inadyn.)

    Tomato/TomatoUSB are the way to go at this point. (Tomato itself isn't updated much either - TomatoUSB has improved support even for non-USB devices.)

      Another vote for TomatoUSB over DD-WRT - open source and very feature rich. The Asus RT-N16 runs great on Tomato - that's what I use and love it but like mentioned above it's only single band.

      • Ditto on the above comments... TomatoUSB + Asus RT-N16 is about the best combo available. I've used RT-N12's as well, but they don't seem to be as stable, and had trouble getting an N12 into bridge mode (would brick itself, sftp for recovery).
    • DD-WRT is not dead but the developers work in the strangest of ways and can't be coaxed toward sanity. If you browse the file directories on the server (many links in the DD-WRT forums) then you can find updated beta builds. The beta builds that we forum moderators recommend is getting old but that is because the newer builds have several major bugs, but you're free to run any build you want.

      Just look at the DD-WRT Trac for proof that it's still being developed. []
