Arris Surfboards supposedly have bad Intel chips in them from what I've read. I went with a TP-Link TC-7620.
Itís not all Surfboards, just the ones with the puma 6 chip, most notably the 6190.
To the OP, any 16x4 modem would be fine. The 6183 is what will get the most recos.
Do you have any electrical issues? The 6141 is considered quite the workhorse and most people donít replace 3 of them.
