I'll start off with saying I have been over the checklist and here is the TL;DR
With TWC-TG1672G, Constant WiFI drops, slow speeds, bridging to a Linksys e2500 fixed all issues but was limited to the speeds of the router.
With Spectrum-TG1672G, Constant WiFi drops, high speeds (150mpbs on LAN/5ghz), bridging stopped the drops but introduced bursts of latency and throttled back speeds making streaming/gaming difficult.
I have a Cat 6A 28 AWG patch cable bridging the equipment for what its worth. Still got the same speeds using a standard 5e.

Starting off with TWC, they gave us this infamous 3-in-1 and we had a terrible time day 1. They kept telling us it would break in and fix itself but never did. I ended up bridging the sucker following a guide and tips from this forum. After the initial bridge everything worked "OK".
We contacted support a couple times about this issue and got into the whole basic trouble shooting dance. Eventually they sent a tech out and all he did was reset the modem and unbridge it which did not remedy anything at all so I just rebridged and delt with it.
Now with Spectrum, I thought things were going to be different. They had us take in all our 'old' equipment for 'new' equipment that looked identical. I slapped that 3-in-1 in and everything looked fine, it was interesting that it retained the old settings from the previous 3-in-1.
The speeds were great, dramtically different. But the problem was everything was getting disconnected around 5 times a day. I tried to fix it with bridging into that e2500 but now the latency spikes are insane.
I don't know what else to do, does anyone have any suggestions?
Solved! Go to Solution.
File a complaint with the FCC. I have been having the same problem for 1 to 2 yrs.

What was the outcome of your FCC complaint filing?

@Albatross11 When you switched TWC's TC1672G modem into bridging mode and wired through your Linksys E2500 router, I can see that you forgot to enable DHCP addressing in the Linksys. Set it to start at 192.168.1.100, and allow 32 devices. Then verify that your new laptop IP address is in the range 192.168.1.100 to 131 only!
Did you also remember to:
Turn off BOTH 2.4 and 5 GHz WiFi radios in the Technicolor? That uses separate commands.
Change the DHCP Lease time to 99999? [it's in seconds,99999 is just over a full day]
** I think this one is causing your disconnects
Next, please tell us about your speed measurements with real numbers:
What speeds down and up do you pay for?
What speedtesting web site or software are you using?
What speeds do you see when your computer is plugged directly into the TC1672G?
What speeds do you get when your computer is plugged into the E2500 router?
What speeds does your computer get over WiFi from the E2500 router?
And last,
Do any of your software applications or games require using IPv6 addresses?
The fields were filled out for the DHCP, it was not limited to 32 devices however.
I know I disabled the band's for the Arris TG1672G. I saw through the myservices portal that they were on and when I used that portal to shut them off everything went down and I can't connect to the modem through a hardwire haha.
I'll give you know info when I fix this mess.
It seems under WAN Setup I cannot disable DHCP, it tells me sit set a static and there is no where for me to do so.
1. I am using the Arris TG1672G and I have, I will mess with the lease time now.
2. Paying for 100Mbps

You are getting good speeds when wired to modem direct and through your router. You are seeing faster than 80 down and 8 up. That's all TWC has to do for you.
Your computer's WiFi adaptor runs very slow on 2.4 GHz and not great on 5 GHz. It might be due for a technology refresh to 802.11 AC.
Here's your issue: Bad router, cable or nic card or it's set to 100 base rather than 1000 base right on the WAN port
LAN Port 1 | Enabled | Up | 100(Full) | AC:EC:80:27:6C:F1 |
The cable is good, tested out multiple, and my computers NIC card is good, is there something I can change in the router or should I swap it out?
this is what I see
