Unreliable modem and terrible customer service 10/24/2017 9:51:31 PM

Pros: High speed.

Cons: Failed to work after a few months. Contacted NETGEAR customer service and they directed me to contact my ISP. ISP inspected and confirmed the problem was with the modem. I tried another modem of other brand and the internet worked just fine. Contacted NETGEAR again and they refused to fix their modem and keep asking me to contact my ISP again. The modem was still under warranty but they refused to take it back to fix whatever problem it has unless I buy the extended warranty. In the end, I had to buy another modem and tossed the NETGEAR one away.
This is the last NETGEAR product I buy. Very unreliable and terrible customer service.

good cable modem, just some minor inconveniences 8/2/2016 4:08:48 PM

Pros: 4 gigabit LAN ports
simultaneous dual band
guest network on both bands
stand with bottom air ventilation
not DD-WRT compatible
works with Xfinity, Cablevison, Charter, Comcast, Cox, Optimum, Time Warner, Bright House Networks
router/bridge mode
on/off button for easy hard reboots

The unit is quite big compared to other cable modem's I've owned. The stand elevates the unit so that there's space in between, allowing ventilation at the bottom of the unit.

This unit was installed using Bright House Networks as the ISP, with firmware version v1.02.20. Internet setup was very easy: connect the coaxial cable, power cable, ethernet cables, then call the cable company to register the cable modem. The specs of the cable modem (MAC Address, Serial Number, Model #, etc.) are on a flexible piece of plastic that can be pulled out from inside the unit for easy reading. Nice simple feature, I don't have to turn the entire unit around to try and read the MAC address.

You can only log into the web interface using one account. The web interface has basic and advanced modes. Advanced features include address reservation, port forwarding and triggering, DMZ, simultaneous dual bands, parental control, separate MAC filtering for both primary and guest networks on both bands.

The menu system isn't very intuitive. Things aren't where I would typically find them and the naming convention isn't what I would typically see on a web interface of a cable modem or router so it takes a bit getting used to it. For instance, the Advanced Setup menu has Wireless Settings, Port Forwarding/Triggering, Dynamic DNS, Remote Management, UPnP, and USB Settings. To find MAC filtering (I had to search their manual for it), I have to go to Wireless Settings and click on a button called "Set Up Access List" next to the heading "Wireless Card Access List". I'm used to seeing "Access Control" under its own heading in the menu. Another example is the primary and guest networks. I typically see them both together; however, this menu separates them into "Wireless Setup" for primary, and "Guest Network" for guest. Not deal breakers by any means, just preference.

The web interface (Netgear genie) includes a feature called "ReadySHARE", which allows you to connect a USB storage device (flash drive or hard disk) to the router and make it available on your network or over the internet. There's an option to enable it to play on DLNA-compliant players.

The Network Map, which is located under Administration (again another odd place to put this in my opinion), is a graphical representation of all the devices connected to your network. Wireless devices are designated by the wireless icon (see con section for more on this). The devices are displayed by their given device name. Unfortunately, the name is not changeable, which could make some devices difficult to identify. Clicking on each device will display the device name, mac address, and ip address.

When adding devices for Mac filtering, you have the option of naming the device, which is a great feature to have. I've had other cable modems that don't have that ability. The page is a bit awkward to navigate though. Each network is grouped by the band. Each band lists the primary and guest networks as radio buttons, which toggles (refreshes) the page and displays the corresponding list of MAC filtered devices. So you can select the 2.4GHz network, the page will refresh, then select the 5GHz network, and the page will refresh again. However, if the page refreshes and you haven't saved your changes, your changes will be undone.

Parental Controls is pretty robust. You can block sites by keyword or domain (there's an option to allow one ip address to visit blocked sites), and block services (includes a large list of services) by ip address or range. By the way, Block Services is basically the Firewall settings (there is no menu item called "Firewall"). You can create different schedules and apply them to the different types of blocks. You can also turn on email notification (requires mail server) for alerts (when someone attempts to visit a blocked site) and logs.

Administrative tools include Diagnostics using ping or traceroute, Wireless Channels (on either band) and the number of wireless networks (along with their names) on each channel, Wireless AP displays a list of wireless networks on either band, along with the security level and signal strength.

Other reviewers seem to have lots of disconnects. Perhaps it's their ISP? I have Bright House Networks and haven't had any disconnects since I started using it about a week ago. Wireless signal is decent. At just a few feet away, the average RSSI peak signal is -46 (excellent signal strength is around -30). At one story down, the average RSSI peak signal is -63.

Overall, this is a very good cable modem, mostly just some minor inconveniences.

Cons: There's a bug in the Network Map. Not all wireless devices display the wireless icon. So it's very difficult to tell which are wired and which are wireless. The only way to tell is by reading the name of each device. This is a preference, but the graphical display of the Network Map can only show 6 devices, plus the internet icon and the ReadySHARE icon. If you have more than 6 devices (wired and wireless), you must go to page 2 to view the rest of the devices. The manual from Netgear's website doesn't match my interface. It says that the "Attached Devices" are located under Advanced - Administration - Attached Devices, and it lists the devices based on wired, 2.4GH, and 5GHz (I prefer this layout over the current one). I have firmware version 1.02.20 (latest is 1.02.21) and the manual is dated Nov. 2015, don't know which is older.

I noticed that if I have MAC filtering on, every time I add a new device to the MAC filtering list, the device will not connect to the network until I disable the MAC filtering first. I have never had to do this with other cable modems or routers.

This is another preference, but the menu system could be laid out better so that it's easier to find things and I don't need to drill down multiple pages to get to one item. Another thing that was a bit irritating is that the session expires way too quickly, about 5 minutes, at which time I have to log back into the web interface.

Overall Review: The wireless guest network (both bands) is on the same subnet as the primary network. Sometimes, in the web interface, it takes a while for the page to refresh. It will go blank for a couple seconds before you see anything.

Because the Network Map wasn't showing any wireless devices at the time (even though it should have), I reached out to Netgear tech support hoping they could shed some light on where the connected wireless devices were located (they only provide free tech support for items that are 90 days old from purchase date); however, they gave me a hard time because the item was "beyond a reasonable presumed shelf life" (difference between manufacture date and purchase date).
