Modem Version
Mallory Chowansky
Firmware is the software programmed into your modem that makes it run. Firmware is updated periodically to add new features and keep modems performing their best. Updates are done automatically through the CenturyLink network, so as a rule you never have to think about it. However, if your modem isn't working properly, you can check to make sure the firmware is fully up to date by logging into the modem settings.
15. Once the upgrade is complete, you will be taken back to the main Modem GUI Login screen. Wait 2-5 minutes for the DSL and internet lights on the modem to turn green before trying to browse to a webpage to test that your connection is good.
DOCSIS 3.1 provides better Internet overall. The biggest benefit of DOCSIS 3.1 is faster speeds and stronger security. Only DOCSIS 3.1 can deliver Gigabit speeds. Other benefits are that DOCSIS 3.1 offers:
The time to have DOCSIS 3.1 support is now. If you are still on DOCSIS 3.0, consider upgrading to DOCSIS 3.1. The Hitron CODA DOCSIS 3.1 cable modem is the perfect choice for any cable Internet user looking to take their connection to the next level.
2.5G Ethernet, also known as 2.5 Gigabit Ethernet, is a standard for Ethernet networking that allows for data transfer speeds of up to 2.5 Gigabits per second. In simpler terms: 2.5G Ethernet supports up to 2.5 Gbps speeds and uses an Ethernet connection to do it....
I purchased the AC1900 C7000v2 cable modem for use with Spectrum Internet a few years back. Everything has worked fine until a few days ago. My instincts told me to update the firmware (currently V1.02.09).
As the Netgear Genie (internet portal) listed nowhere to update the firmware, my investigation lead me to download and install the iOS app and waste time setting up an account. After installing the iOS app I was excited to see the app confirm that the firmware was out of date... but gives absolutely no way to download and push it to the modem. I was frustrated and annoyed to discover that other uses have had the exact same experience with Netgear offering no specific solutions - especially for this model.
Right now it's all working and the page you suggested I look at shows that the firmware listed above is the only firmware approved by Spectrum even though 2 newer versions are available. As mentioned I haven't had a problem today (and I think that the real issue was on Spectrum's end).

well I tried to download some changes after a while on one V1040... visilogic asked me to update the controler OS because it was old and I did. that result a fatal error on startup, so i deside to update it again using usb cable and not network connection this time. During bin.lib update i accidentaly lost communication and from that point and on all went wrong. with Unitronics Support I restore the controler with the lettest system files, bin, boot and os. I download the project and after that the fatal error was back!
I took out the battery to zero the memory becasue the project was not burned and starting again with out application I download again the project. the fatal erros was there again so I deside to give "some time to the air". turn off the power, let the battery in controller and I went for a coffee.
and it works! after power up the plc it boot ok and is fuctional but not 100%. the GSM intigration which was connected on Port2 has no communication with the TC35i modem. the led in front of port 2 are blinking, the signal is good and when i call the modem answer. so i tought to change the port from 2 to 1, i made all the nessesary changes on the program, swith the modem cable to port 1 and download, reset and run the plc.
the only thought that i cannot execute because i'm missing files. is to roll back everything. find visilogic v.9.8.80 where is the last project backup and all the plc system files that response to that but I don't have them.
Part of your "story" implies that you don't have the original project, but how did you then do the mods without it? The mods might be the cause of the issue. Perhaps the original project is stored on the SD card if it has one.
what is strange is that when i update OS (VCO00401044_V1040)over ethernet and had the fatal error, i roll back the os again via ethernet connection (VCO00401036_V1040) and it boot and had a sms from the PLC that it was LIVE again, and it was fully functional.
At the beginning of my work with Unitronics, I read a message from Flex that the most correct is to use the controller firmware with the version of the Visilogic program in which it was created and burned. To do this, Flex has a set of versions with the ability to quickly switch.
We must state the fact that developers are constantly moving forward, as they, like Henry Ford, could release the same model of machine (PLC) for another 20 years, but changes in the Visilogic environment need to modify something in the firmware - so the transition from the old program to the new version Visilogic and firmware must be justified and tested .
Software and firmware version control is critical when working with industrial components. Always check and never upgrade unless there is a critical need. Further, always keep a backup copy of any previous version before upgrading, if that does become necessary.
Those files come with the VisiLogic software installation. VCO00401036_V1040.UOS came with VisiLogic 9.8.94. All the files you seek are in VisiLogic installation folder, however, you just need to startup VisiLogic, confirm you can go online with the PLC, then have VisiLogic install the firmware.
Install VisiLogic 9.8.80 and you'll have all the firmware files you need. If you opened a 9.8.80 project with 9.8.94, VisiLogic should have automatically saved a version of the project with the file extension .1.154 (instead of .vlp). Change that file extension to .vlp and you have the previous version as it was before you changed to to 9.8.94.
I connect it direct to PC Com port (once on desktop pc direct com port and once on laptop using usb-serial converter), from Visilogic's Modem Services I tried to do initiate it without success, Communication was not possible. i tried also from a serial terminal to command it without success again.
I 'm not 100% sure that i did everything right because it's been a long time since I setup my last modem, but i think i did.
My only comment here is that W10 has somehow done something to running my com port on the m/board, such that certain actions in Visilogic like an O/S load and other programs usage of the port have stopped working properly. I haven't had time to pursue the reason as yet as I don't do the actions needed very often so it can wait a bit. I have W10 updating blocked but some things appear to slip through now and then as M$oft constantly change the way updates are controlled and done.....no doubt to counter all the people blocking things for some control over the process!
The relevant point is that after a few attempts at something that should have worked immediately and didn't, for curiosity's sake I shifted over to doing things on one of my W7 laptops, and things work perfectly. (In writing this I have realised that at the time I didn't try things on the virtual W7 system on the same computer.....that must have been a severe brain fade day. I'll first have a go at this method during tracking the issue.)
