    Which cable modem should i get? What brand is best?

    I have a motorola surfboard now (had it for 8 years) and i think its about done. I was thinking of just getting a new one but i was going to check here first.

    Thanks guys,

    I can't say this is the best cable modem out there, but speaking from experience, my Linksys BEFCMU10 v4 has been great.

    It is DOCSIS 2.0 out of the box and consistently gives me faster than rated speeds on the download side. My connection is 6M/384K. Downloads are usually in the 7-8Mb range and uploads are about 355K.

    I originally used the BEFCMU10 v2, but it would never go beyond 5Mb download speed, probably due to it being DOCSIS 1.0, so I decided it was time for an update.

    The info pages ( are also probably some of the most detailed out there. If this is important to you, it should fit your needs well.

    Thanks for such a detailed reply!!

    One more quesiton though, where can i get it and how much?

    How much did you pay when you got it?

    I saw this on Buy.com and it was DOCSIS 2.0 but it also said it was v2. So are you sure there is a v4 cause if not then buy.com is selling an old version that they are marketing as DOCSIS 2

    I bought mine from newegg.com. Says v4 right on the bottom of it. Only $40 after $20 MIR. Good deal. Still available I believe.

    Unfortunately there are no guarantees that you will get the v4. Some people say they are still receiving the v3, and although both are DOCSIS 1.1 & 2.0 Certified, the v3 comes preloaded with DOCSIS 1.1, while the v4 gets 2.0. There is also the possibility of different firmwares being loaded. That is up to your ISP.

    The best a v2 can do is DOCSIS 1.1. It's DOCSIS 1.0 Certified, Upgradeable to 1.1. Mine always stayed at 1.0, and some people claim to have seen 1.1, but never 2.0.

    It's possible buy.com only updated the DOCSIS info on thier page, and not the version. I mean, the v2 is from 2002. That would be some pretty old stock for a company like them to have around. But it's not impossible.

    I would start by calling your ISP to find out what modems they support. I just happen to run all Linksys for my networking needs, and Comcast supports them.

    Good luck on your purchase.

    So if my ISP only runs on DOCSIS 1.0 or DOCSIS 1.1, then i don't have to worry about getting 2.0?

    Oh just FYI, the one on buy.com says its 1.0 and 1.1 upgradable, so i was mistaken that it is NOT DOCSIS 2.0...

    You don't need to worry now, but it would be beneficial to have one that is 2.0 Certified. That way if your ISP upgrades, you will be prepared instead of having to yet again, upgrade the modem.

    I have to recommend the Motorola Surfboard 5120. I just had a Linksys v4 act up...badly. It would not transmit to any wireless router faster than about 250KB/s. Swapped it for a Motorola 5120 and my speed is way up with Comcast...around 1000KB/s
