TylerUC :
I am going to be getting Spectrum internet service. They are advertising that I can get a modem for free but need to pay $5 a month to have WIFI enabled so I was thinking of buying my own equipment to try and get a better quality modem and router and avoid the wifi charge.
I have been doing some reading and a preliminary decision on a modem is the
TP LINK 7620. Do any of you have any comments or advice regarding this modem?
As far are a router goes, I have looked at them a bit but have not decided on one. Any suggestions in particular or things I should look out for? I was thinking maybe the
TP-Link AC1200 (Archer C1200) or
Net Gear R6100-100PAS.
You should definitely get a separate modem and separate wifi router. Spectrum is going to start upgrading markets outside Hawaii for gigabit Internet in 2018, and a 16x4 modem won't cut it if you want to get higher bandwidth when it reaches you. Also, the 802.11ax standard may be on new routers next year or in 2019, and that will be better for throughput than 802.11ac (not nearly as good as 802.11ad at 60 GHz, which you can find in some routers today, but 802.11ax at 5 GHz would have much better propagation characteristics over air than 802.11ad). Keeping them separate lets you upgrade incrementally (I usually sell old stuff on eBay when upgrading).
The C1200 and R6100 are mediocre in the RAM department (just 128 MB), and the R6100's transmit power is only 390 milliwatts and its CPU clock speed is anemic at 560 MHz. Plus, both of those are just 2x2 MIMO, so throughput will be lower (all other things being equal) than a 3x3 or 4x4 MIMO router (see mcsindex.com).
If you want to stay in the $60-$90 range new or refurbished or used, you can check out the D-Link DIR-880L and TP-LINK Archer C2600. The DIR-880L has a 800 MHz CPU and 256 MB of RAM, the C2600 has a 1.4 GHz CPU and 512 MB RAM. Both have transmit power above 970 mW on both 2.4 and 5 GHz. And you can upgrade the antennas for higher gain if you need some extra coverage. The DIR-880L is 3x3 MIMO and the C2600 is 4x34 MIMO, so that's 50% and 100% more throughput in Mbps respectively than the C1200 and R6100, for about the same amount of money.
