Looking for new cable modem

Rich McCabe

I recently replaced my modem with a Arris SB6190. I have been unable to use port 23 for telnet since. Arris is zero help and Mediacom says they are not blocking Port 23 and to talk to Arris.

My Motorola modem worked OK but I could not get it to work in bridge mode so as unable to connect my Ubiquity Firewall/router to it.

So back to the drawing board as being able to Telnet on 23 is important for a ham

Suggestions appreciated for ham use.  I personally would rather it be basic as I have the routing and firewall covered.

This is a Mediacom cable 100MB cable connection.

Hey Dave,

Yea I started with the Mediacom supported list. I don't want to battle with them anymore than I have to.

I took the router/firewall out of line as normally a port restriction is a function of the router and not the modem. So I just took a notebook down to the basement and plugged straight into the modem. Internet was OK but still could not telnet a cluster server. Can telnet VE7CC.net on 7373 but not 23.

So either the modem is blocking the port or cable company is. Mediacom says they are not and so does Arris.  And the support ended there.

The SB6190 is just a modem only so there is no router in it. So when you log in you have option to change PW and logs.

I just ordered a Netgear CM1000 and it should be here Monday. I have just read all kinds of stuff on here about modem issues with the Flex so thought I would make a post.

Previous modem/routers had no issue with 23. I just cant be sure if it stopped working exactly when I upgraded some network equipment or not as the cluster I was using was not a standard port 23.
