Battery Light Flashing On Spectrum Router

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

As many others mentioned in the reviews, these batteries are now new old stock, as the newest ones were made in 2022 and will arrive completely discharged. DO NOT give up on them - the charger will initially show an error (chamber and calibration light flashing) - keep taking the battery off and putting it back on, and eventually it will start to charge. The key is to not leave it in the charger if the charger is showing the error code, you have to remove and replace the battery until the charger shows that it is charging (chamber light and 50% light flashing). After a few hours the 50% light should glow solid and 80% should start flashing, and eventually it will charge fully

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

I bought this a month ago when the battery died (I unfortunately did not notice the low battery flashing light indicator). The replacement battery arrived very promptly, was easy to install, and my backup is operational again — and just in time because a tornado hit here a few days later and I lost power for 8 hours.

but it is unsettling to have the upstream light flashing

Router is simple and faster than my previous D-link at 150mbps.I like that I don't have to see all the flashing lights.

This router is a great router combo at an affordable cost. Works well with Spectrum!

I upgraded my router from spectrum base model to this lovely nighthawk.. I was noticing lagging and traffic usage was slowing my spectrum router down.. the nighthawk router help my speeds by 200 mps but lowered my ping and can use all my devices without lag spikes! Most get in modem and routers

5 stars! Stable and very easy to adjust level with slider on.

Great switch from the standard router you would rent from Spectrum. Was having issues connecting 2.4ghz devices to the basic router from them. Bought this and didn’t realize how slow my WIFI was with their router. With the AX4200 my wifi speed is amazing, videos stream better than ever, gaming is much easier and I can now connect my Roomba to my wifi. No complaints so far! Their NETGEAR app also has a ton of features, albeit many that I might not use. However, it is nice to have those options! Thank you!
