I regret not noticing my modem was the cause
I regret not noticing my modem was the cause
I never thought my modem was the problem. For four years, my internet kept dropping. I tested everything—maybe the router was slow, maybe my devices were the culprits, or perhaps the 400Mbps plan wasn’t enough and upgrading to 600 was necessary. It could have been the CAT5e cable. I changed everything except the ARRIS SB6121 I got in college. I thought it couldn’t be that bad since it supports gigabit speeds. But yesterday, I switched to an ARRIS S33 and the difference is clear: no lag, no dropped calls, and speeds matching my plan. I’m hoping someone as clueless as me will understand this after getting a new router every three years.
LAN performance from DOCSIS modems doesn't match the real coax speeds listed. Verify the provider's modem specifications if available, as they may claim higher rates like "600Mbps" while offering only 100Mbps LAN ports on each side.
Some metaphors here, if a router has two hands it can only transmit or forward two units of internet data each second, but if it has six hands it can move six units per second. No matter how many buckets you're given—two, six, or fifty—it still moves so slowly.
Docsis truly stands out on its own, and it's reassuring that the issue was resolved with an updated or more powerful modem. They’re now capable of handling the expected speeds and should last longer with planned upgrades like the S33. The current setup supports DOCSIS 3.1, offering around 2.5Gbps down and roughly 400Mbps upload—though some estimates suggest up to 500Mbps upload. It’s interesting how the provider allowed this modem on a higher-tier plan, showing some level of commitment beyond just profit.
It might involve components such as a wall wart adapter or internal DC-DC converters failing (like capacitors wearing out), which can add unwanted noise into the circuit. This noise may impact the processor and diminish its capacity to interpret signals from the coaxial cable.
In retrospect, they attempted to convey something, though they did so by urging me to lease their modem, which I dismissed as a quick profit opportunity.
