I have been trying to work through the Mediacom forums, but responses are slow (and terrible). Here are the thread link (hxxps://forums.mediacomcable.com/index.php?topic=33412.0) and info:
Me to mediacom:
It is a computer. I have rebooted many times. I also set the ip to what it had before and it didn't work. I ran tcpdump on the interface plugged into the modem and see dhcp requests, then dhcp discovers, then it waits a while and starts over. It is not getting a dhcp response at all. I changed the MAC address on the interface and tried it all again. No responses. I see a lot of arp broadcasts from the cable modem wan side, so I know the cable modem sees traffic from you. For whatever reason, your dhcp server is not handing out an address. There really isn't any more I can do on my end.
@MediacomChad - can you help please?

[Cable HSI] Question about Mediacom Firmware for SB6190
Over on the Comcast forum, they have released a new firmware version 9.1.93N for the SB6190.
https://www.dslreports.com/forum/r30763596-Firmware-SB6190-new-9-1-93N-firmware-update
Is Mediacom rolling this out? And if not, could I potentially connect my parent's SB6190 to a Comcast connection, let it download/install the firmware, then connect it back to their Mediacom service, and would the firmware remain updated?

[Cable TV] 827- NBCSN Hockey Game showing on HDTV in Wrong Format
It's a full HD transmission, but Mediacom is showing it with both sides squeezed up, so the players look tall & thin. All other 800 HD channels are OK.

[IA] Possible DNS issues?
I had to replace my old modem yesterday and took it into the local office and got a new modem. Once home, I hooked up the modem and called and got it activated. Today, while on my PC using an ethernet cable directly from the modem, I'm noticing that sites are loading slowly, some images are showing up broken and video isn't loading. I'm using Google chrome and getting error messages such as: "The operation timed out" on embedded videos and images.
Any help is greatly appreciated.

[MO] Any thoughts on what is causing my VERY VERY SLOW connection?
Hello,
My Mediacom internet has slowed to the point where if feels like it is slower than an old-fashioned 300 baud dialup.
I originally thought perhaps it might be related to my home network, but even plugging directly from my cable modem to the computer it is just as slow. I am using a MacPro Desktop computer running OS 10.11.4. I have been a Mediacom customer forever. The cable modem is a Motorola Surfboard 6121. The problem is constant. Time of day does not matter.
I have a technician coming this coming Monday, but I was curious to know in advance what some of the possibilities are that might be causing the problem.
Most of the time I can not get SpeedTest or PingTest to complete a test. On one rare occasion I was able to get the ping test to complete. Attached is a screen capture of that test.
Any thoughts? I am just trying to educate myself for when the technician comes to the house.
Thanks!

[IA] Summer bad speeds again
Seems every summer we upgrade equipment to try and fight off the bad speeds. They used to say squirrels because our trees were in them, but we have not had trees for two years. Tech will come 2 to 3 times and says nothing is wrong. Then about 3 months later we will get a message a problem has been fixed in your area. Well, we are back to it again all winter we get 166mbs and right now are down to 3mbs. I reset the whole network about 4 times a day to to keep running. When its going good it will run for months without errors but now it logs thousands just like every other summer. Last year Mediacom chad sent me a modem and it did not help until the problem was cleared. we bought sb6183 seemed to work a little better. The year before got a linksys rt-ac68u to try and help.

Another Modem/Router Question
Hello!
I recently signed up for MC internet and I would like to purchase my own modem / router combo rather than renting. I've read a few other threads here asking for recommendations for modems, but haven't (yet) seen a thread that would help me out.
What I would like is a modem/router combo, but..
1) No wireless
2) No firewall
3) If wireless/firewall, a bonehead simple way of disabling them
4) If needed, a bonehead simple way of opening / forwarding ports
5) 4 ports
Biggest issue about the router portion of the modem/router combo I am worried about is needing to open ports so that my PS4 / XB1 don't have issues connecting to games, so that is why I would prefer a combo that doesn't have a built in firewall/wireless option.
If such a modem/router exists, and I buy one, how would I go about getting "provisioned" for MC? When the tech come out to install the service, he at first wanted to install a modem/router combo, but he said I needed to sign-up for MC's home wireless service in order for the other ports to work, since the mode/router had been "baselined" so that the extra ports were disabled.
When I go to hook up this new modem/router I want, will there be a chance the during the provisioning process that MC disables the ports on my hardware? I know that sounds kinda paranoid, lol.
Any/all suggestions would be appreciated! Thanks!

[AL] AL - Spanish Fort - Constant disconnections
I would post speed test/signal/etc... but I am at work and for the last two days my modem has been constantly disconnecting. I don't know when this started as I have been on vacation. Sometimes it stays disconnected for 5-30 minutes, sometimes it comes back right away. I see the modem connection lights indicating desync and resync going on and off, or whatever you want to call it, loss of signal. My internet is pretty much unusable.
Got access, here is what its doing, sanitized MAC addresses, can PM if needed.

[IL] Billing Error......again.
My bill for Ultra went up $14 and is now $88.99 for this current period. I stared comparing statements and I am now being charged for High Speed Basic @ 14.04. I have never been charged this before. It has only been Prime+ to Ultra (SB05) @15.00 and then Prime Plus HSI @59.95. What's going on here? I've attached the pdf's if anyone can check them out. uid://1705265

[IN] Availability
I had cable internet scheduled to be installed this past week as I was told it was available. When the tech arrived he stated there was no equipment to hook up to. I was then called and told it would need to be sent to construction to get an estimate. I don't believe I'll hear back. A there anyone that can find out for sure? Chad?

More Upstream Channels
Just noticed I now have 4 upstream channels, looks like they went up last night. MC Chad...can you verify how many downstream channels my market is running now? I can see 8 with my 6141, but am curious if we can order above the Ultra Plus level now that we have the increased upload capacity. We have been running 8/2 for the past few years. Would of course need to upgrade the modem to take advantage of the additional channels...but want to make sure they are there before spending the money on a better modem. Thanks!

All Upstream Channel transmission rates have now been cut in 1/2
4 Upstream channels at 2560 rate seem to offer no benefit over 2 Upstream at 5120 kSym/s.
What is the benefit of making 4 channels with only 10 Mb/s bandwidth when we had that with 2 channels at 20Mb/s from a congestion standpoint?
