a 'Superior' cable Tech that ownsone went through the same thing

While the SB6183 is not cutting edge technology any longer, it is one of the best cable modems I have used.

This is an excellent cable modem.

I sent it back and bought the Netgear C6250 cable & modem router combo, which works great

Able to handle plenty of speed that any normal home use would require (only going to be as fast as the cable speed you are purchasing).

Perfectly fine modem but who the heck doesn’t include a cable!?!?

Arris has plenty of workable cable modems for 50 mps service but this unit did not work.

perfect cable modem, it's been up for weeks not a single hiccup

Super fast cable modem!

no complaints really cause arris (Motorola owned) makes great cable modems

Very reliable cable modem.

Do not forget that higher wired speeds need better cabling too so all wired cables should use cat5e or cat6 cabling

Excellent stable cable modem!!

The SB8200 (CM8200) series is the best cable modem for DOCSIS 3.1 that is widely supported at the time of this review

This is a reliable Cable Modem with excellent Enet speed.

While this may be a good Gigabit/DOCSIS 3.1 modem, it has a critically flawed firmware that is vulnerable to the Sagemcom Fast 3890 / "Cable Haunt" exploit

I purchased and installed the SB6183 when my cable provider (WOW) told me that the reason for the poor throughput we were seeing was that we needed a DOCSIS 3 modem

Its a very compact yet very powerful cable modem

Called Amazon and they are sending me another one but don't except used items to work as they are probably associated on a different account

Evidently the DHCP doesn't work as you'd expect (i.e. modem is online, connect a router, router asks for and receives an IP address).

When I unscrewed the coax and pulled the plug and let sit for an hour and then hooked everything back up everything worked as it should.
