Ever since my downstream channel was moved from docsys 3.0 to 3.1 my speeds refuse to go over 250mbps down. I have the 300/30 package and would average over 400bps down. Using the arris docsys 3.1 modem
Have you tried a factory reset? Most modems will have a hole/button on the back you can push with a toothpick/paperclip to factory reset the modem. This clears the configuration file, which holds the memory of what downstream channels the modem should use. After the factory reset, you will often have to power cycle your router. If a factory reset doesn't fix the issue, perhaps a moderator here can re-provision your modem.
What model modem do you have BTW?
I have the sb8200 and reset it a few times already. I've done a refresh but not sure of ive done a provisioning. My network at home is fairly beefy. Full cisco meraki setup with a ubiquiti mesh wifi network. The only thing that changed through all of these was the docsys 3.1 light turning on for downstream. I read about a firmware compatibility somewhere. Trying to avoid calling support as they will most likely just want to send someone out for something that can probably be fixed remotely
Sounds like you know what your doing then, and even have the right idea how to get it fixed. Doesn't sound fun though. Tier 2 can still do firmware updates, but that's assuming they have a patch and that's assuming it's a firmware issue. Could just be growing pains of the D3.1 systems themselves.
In any of the factory resets, when you looked at your logs, did it show it downloading the configuration file? May be abbreviated to "CFG. file" but should be some mixture of a word with some letters and numbers. Either way it will end with a number which is your download speed and number of IPs. So Ultimate might be 34001 for 300Mbps + over head + 1 IP address. Overhead is because they assign a bit more speed then you should get for the natural loss occurred in the use of DOCSIS. If you can find what the configuration file loading on to your modem is, you can see if your speed issue is related to it.
Genius. I will have to dig through that tomorrow. If you watch the speed test you can see it wasn't to go past 250 but it won't. Something is definitely odd. Thanks Again!!
Is this you?
If so, I would factory reset the R6250. It sounds like it might be hacked and gave away your public IP address.
So I am confused. Is the thread above not you? Because if it isn't they are having a similar problem. I wonder if there could be some security issue happening with that model.
Ive only posted once. Sounds like someone else is having a similar issue. I heard somewhere of a firmware issue but not the modem. It was a thread on reddit I read.
This is not me. Sorry.
