A:AnswerThis modem is compatible with Spectrum's "Internet Gig" service at 940 Mb/s speed; which is what I have. You need a separate modem for your phone line. I use an Arris model that was provided by Spectrum. If you have a modem for your phone line, you can (and should!) continue to use that for your phone line.
A:AnswerThe Netgear CM2000 has worked great with the Asus RT-AX86U for me. I settled on the Asus router and was satisfied with its performance soon after upgrading to a 1 Gigabit service plan with Suddenlink. Getting a capable modem that connected and performed at an appropriate speed was more of a challenge. After failing to get anything close to the 980 Mb rate claimed to be available with the 1 Gig service using four prior 32 channel Dox 3.0 modems, then Arris' S33 released about the same time as the Netgear CM2000, this Nighthawk modem finally provided the speed Suddenlink indicated I should have. Four technicians were sent by Suddenlink over a month-and-a-half, because none of the support personnel were able to provide substantive help over the phone for the other modems' slow performance. The cable lines tested appropriately with a strong clean signal, but several of the modems topped out around 100 Mb (including the Arris S33), while a couple reached a mid-300 Mb speed. Both the CM2000 and Asus RT-AX86U were difficult to find and purchase during the final months of 2020, but when Best Buy finally showed availability of this Nighthawk modem, it dramatically increased the speed Suddenlink said I should have to an acceptable level for the first time. I've often tested speeds from a mid-700 Mb range to sometimes reaching upper 800s. The 900-plus Mb speed has remained unavailable, but a couple of the technicians mentioned that we're in a highly saturated service area where many neighboring households share the cable bandwidth, limiting its theoretical speed. After a tiresome process to get the upgraded internet speed with Suddenlink, the Netgear CM2000 has performed ideally with the Asus router you've asked about. We are getting strong Wifi 6 speeds on a couple of laptops along with solid, consistently lag-free performance on phones, tablet, and smart TVs. The performance and capability of the Netgear and Asus together are about as future proof as you're likely to find in this field.
A:AnswerIt should work well with your Optimum service. I have Suddenlink as my provider in the North Austin metro area, and Suddenlink and Optimum are related divisions under Altice as the parent company. This was the first modem to provide anything close to the 1 Gig speed I upgraded to late last year, after five other modems were tried with miserably slow performance. The Netgear CM2000 was the first to give anything approaching 1 Gig speed with some readings registering mid-to-upper 800 Mb download speeds.
A:AnswerYes. I have the same problem only with the downstream channel. It seems to cause loss of IPv6 when using my XBOX Series X. Power reset only temporarily fixes the problem.
A:AnswerIt can but... Streaming problems vary widely from application to application IE what’s your cable plan giving you for UPload & Download speeds?
Do you have upgraded Ethernet cords cat7 or better yet cat8? The list goes on.. Is your Router up to date to match this 3.1 Modem? your modems ONLY the bottleneck IF you’re replacing an older 3.0 modem & everything else is upgraded to match it.. etc etc
A:AnswerThe modem is capable of linking speeds up to 10GbE however it only has a 2.5GbE port so that is the bottleneck. I haven't seen consumer modem with a 10GbE or SFP+ port necessary for greater than 2.5GbE connection yet.
A:AnswerYou will need to call / check online to see if they work with this modem. I have also learned that just because it states it works with certain providers, does not mean that the providers actually used this model / make. Verify before purchasing
A:AnswerHave you checked and make sure the software is up to dates? The Arris is not particular about the connection while the Netgear actually has a measuring device you can see on the Admin interface. I had the same issue when I went from the Cable providers (cheap version) to the Nighthawk and took them 6 months to figure out that the problem was on their side.
