Motorola SURFboard SB5101 Cable Modem (515290-087-00)

I especially like the product because it provides fast communication in comparison to other modems I have used. I bought the item because I had moved to a location where dsl service wasn't available, and I required something fast for the cable internet. This product fills the need very well.

This is not my first cable modem. I've owned a 3Com "sharkfin", two very early model Motorola surfboard's (SB3100 and SB4200), a Teryon, and up until now a Scientific Atlanta.

I bought this SB5101 because I was tired of getting TCP resets from dropped packets on the Scientific Atlanta. It was also starting to affect the reliability of my VoIP phone service through Vonage. Oddly, my cable lines appear clean (the house is only 3 years old) and are buried outside. However, one of the things I noticed was that both upstream and downstream signals were close to their limits (-2dbmv downstream and 50dbmv upstream). I knew this was not ideal. However, I was irritated that my Scientific Atlanta would not let me look at any of the details of its configuration or its logs. Soooooo, I new I wanted a new modem, and that I wanted one of the best, most reliable, and most user friendly cable modems on the market, the SB5101.

This new modem plugged in very easily in place of the old unit (of course), and with the assistance of my cable ISP, was active in under 5 minutes. My only complaint is that the information with the customer serial number and HFC MAC address are printed too darn small for my aging eyes (without my reading glasses).

Since activating, I have had no dropped or missed connections. My upstream connection is now at 45dbmv and my downstream is at -4dbmv. My signal-to-noise ratio is running at 35db. All of this is well within acceptable levels of operation.

I love Motorola cable modems. They are the Cadillac of DOCSIS cable technology.

If you are looking for a good modem, buy this one!!!

Motorola SURFboard SB5101 Cable Modem is the best modem you can get no matter which cable company you have. It is so good that it will even take weak signals and turn them into good working signals. Motorola has always been the leader in modems for cable company's nationwide. If you are planning to buy a modem don't go for anything other than this modem. It meets all the industry's highest standards and gives you the highest possible speed. You will not be dissapointed. This is the best modem I have ever purchased.

seller was fast on sending out item did not have absolutely nooo problems, very trust worthy and reliable. Item was as seller said, original box and great shipping, seller was very fast!!

Tested and approved. This modem is by far the mos dependable I have ever owned. I recommend this to anyone.

great product, haven't break down yet. it gets the job done while sleek and fit into compact spaces. The only problem is that comcast has to install it themselves over the phone if you bought it from a non-comcast related seller.

I wanted to replace my existing SURFboard SB50101 Cable Modem (515290-087-00)to eliminate my monthly rental. It turned out to be a great decision. Thank you. Look forward in doing business with you.

Works great and cost way less than what they charge you in a retail store. Works well with comcast cable even though comcast is a monoply that over charges its customers for mediocre service.

Excellent modem. It connected without a hitch and provides great speed.

The package contained the modem, an ethernet cable and the charger. It is compact, lightweight and serves the purpose very well.

looks and works great. The small size is nice.If you have comcast for as your internet provider you have to call them and have tham add this modem to your account before you can get online.

Works very well, recommended by our cable company for reliability! This surboard cable modem is easy to use and very easy to install!

The product is great! Recommended. Had an older model & got this model because it was was trustworthy.

This product is great and the sender was fantastic in shipping out on time. A Great ebayer and I would buy from him again

I like the product.AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Very good business person,we had a problem with my order,eventhough U.S.P.S lost my package. this seller went the extra mile for me and re-shipped my order at no cost to me. sellers like these are hard to find. thanks

There is not too much to say about this item, everything is fine with the selle and the item, it is in great working order, As described.

I like the fact that comcast won't be charging me a tax on a tax as they are acustomed to doing. My modem works extremely well. I'm happy I made this purchase plus recieveing it was fast as well...

I bought this modem because it is compatible with my ISP. It works perfect and now I don't have to pay the cable company a rental fee. They also sale this unit at a rediculous inflated price. My eBay seller had it at an unbeatable price and I received it the next day after I paid for. I love my purchase. :)))

Seller was very fast and product came as described. You can tell that the modem is a bit used, but it works fantastic. A one minutes setup may be required if you cable company doesn't automatically recognize the modem. Just call and they will get it activated.

I like that this product is very cheap and I love these modems, but the only downside is that most ISP nowadays give you a modem included in your plan so no point in buying one, unless your gonna hack it which can be very dangerous. I personally regret buying this product, atleast the power adapter is better than the one provided by my ISP.
