Thanks for the info.

I've seen that site before so I might check it out.

My router/modem has a log. Its loaded with errors I can't interpret. I
googled a portion of it and landed on TWC forums. 

Missing BP Configuration Setting TLV

http://forums.timewarnercable.com/t5/Connectivity/Predictable-disconnects/td
-p/1016

Didn't see much of an answer.

Hopefully it's a temporary thing as it just started.  I don't think
it's a
problem on my end, maybe, but doubt it. I'll give it another day or so.

Thanks!!

Hi,

What kind of cable modem/gateway do you have? Just wondering because my 12 year
old Toshiba finally
crapped out and Spectrum gave me a new one. Its and ARRIS TG1682G and it only
gives me a private IP not
like the old one which gave me the public IP so I can't ssh to home from
work anymore, so I am wondering
how you do it?

Thanks,
Steve

I bought an Arris Surfboard Cable Modem/Gateway instead of leasing one from
them for $15/mo.

https://www.newegg.com/Product/Product.aspx?Item=N82E16825122014

I don't use the WIFI as I already have a wireless access point connected. It
does have a 'guest' feature but I haven't gotten around to setting
that up.

for Comcast/Xfinity, I'm using a Arris SB6183 that I got at Costco.   
this is a simple modem/bridge, so /my/ router behind it gets the public IP.

I have a spare SB6121, which is DOCSIS 3.0 up to about 130Mbps max (my 
current internet is around 180Mbps).   I'd sell this for $30 + S&H, 
contact me off list.
