The Linksys BEFCMU10 version 3 cable modem was our solution to a strange bandwidth problem. We noticed our Internet was impossibly slow at certain times of the day. Charter Communications (ISP at that time) sent techs to diagnose the problem, but they couldn’t figure out what was wrong. The signal was fine, they even swapped modems with another one they had with them.
This had us stumped until we realized there had been large powerful thunderstorms in the area around the time we started to notice the trouble with our bandwidth. Turns out the Charter techs had swapped my fried modem with another one that the storms had fried. So both had the same low (made dialup seem fast) bandwidth.
We only found all this out after we replaced the leased modem we had from Charter with the Linksys BEFCMU10 v3 on the advice of a network administrator friend of ours’ (Steve from ATCMI). This was all several years ago in maybe the late 90’s.
The Linksys corrected the problem and provided up to about 8 mb down and about 2.5 mb up of bandwidth in our testing. This might have been due to our router as we have heard the Version 3 is capable of much more bandwidth than our tests have shown.
Overall we used this as the main modem for our business for over 5 years with no problems. Our net connection is used to the fullest extent. We run VoIP and constantly use ftp for uploading and downloading not to mention typical Internet use and then there are Netflix and other video streaming sites such as YouTube.
We feel the average user will be very happy with this modem. Be aware, you may want to look for a modem that is DOCSIS 3.0 compliant. Many cable companies are moving up to this standard and you could see significant gains in your bandwidth without having to pay more for your monthly bill.
