Netgear M1 reboot issue Resolved!i found the real problem that relates to router reboot "randomly reboot" was from your country network band ,Tut: 1- go to admin page2- sign in3- go to settings4- go to advanced settings5- go to Cellular and scroll down6- select your network manually7- now in Cellular page the Band region is Automatic by Default Change it to "LTE ALL"8- reboot your router9- nothing ;Dhave a nice day :)bye

This might not apply to everyone with the reboot issues, but it may help some of you. I'm using my M1 as my main home router but having the flexibility to disconnect it from my network when I want internet access on my travels. For use at home I wanted to remove the battery and power it solely from the supplied 2A mains charger.I have an Ethernet connection from the M1 to an unmanaged Gigabit Ethernet switch, to which I have 2 access points attached for extending my Wi-Fi coverage throughout the house (the Wi-Fi coverage from the M1 isn't very extensive). I also have an external Poynting XPOL-A0001 omni 2x2 antenna attached to the M1 via a couple of short SMA to TS-9 pigtail adapter leads, in order to achieve a strong (5 bar) signal into the M1. However, the M1 constantly rebooted, and the reboots were often triggered by some activity like starting a file download. If I put the battery back in and kept the charger connected, it didn't reboot, but this wasn't ideal because it meant removing the charger when the battery was 100% charged and then replacing it before the battery got too low! I read other threads suggesting replacing the mains charger with a more powerful one, so I purchased a good quality charger with Qualcomm Quick Charge 3.0 technology - this is backwards compatible with the Qualcomm Quick Charge 2.0 enabled chip in the M1 and is able to supply 2.4A. I also replaced the charging cable with a high quality one from the same manufacturer. Since doing this, the M1 interface reports that the session has only been disconnected once in 5 days, and this might be the mobile network provider that caused the session to be disconnected rather than the M1. When I check the M1 browser interface Settings > Diagnostics under the Device heading I can see that the "Battery Charge Status" is indicated as "QuickCharge", so it has clearly recognised this technology in the charger. Obviously, supplying the higher amperage of 2.4A does raise the temperature of the unit, which can also be seen in the Settings > Diagnostics: Device section. My M1 was reaching 41degC when performing heavy downloads, dropping to around 36degC when idle. In order to reduce this, I removed the battery compartment cover and raised the M1 off the surface a few centimeters to allow a flow of air into the battery compartment. I also placed a old CPU heat sink on the top of the unit (with a bit of cling film between to avoid damaging the screen). The heat sink is probably "overkill" but I managed to drop the temperature range by about 5degC (31-36degC), which I guess should be acceptable. So if you too are using the M1 as a static router in your home, this might be a solution for you. However, please be aware that you will be doing this at your own risk. I've no idea how using a different charger from the one suplied would affect warranty, or for that matter the lifespan of the M1. There are many poor quality mains chargers on the market that can damage equipment. It's up to you to do the research to make sure you have a reliable brand. Good luck!

Hope this helps someone.Basically, the issue is that the 2.0A rated charging block that came with my US-based AT&T Nighthawk MR1100 does not provide sufficient power to a battery-less device. ===============================I ran several tests, with one channel running (2.4 ghz radio turned on, 5ghz radio turned off). Once I stream a video (like Youtube) onto just one connected device, the Nighthawk does not play more than 6 seconds before rebooting (often in less time). If the Nighthawk does not reboot in within the 6 seconds while streaming, I simply turn on the device's LCD screen (set to 50% brightness) to trip the Nighthawk reboot.I have a Samsung Galaxy S7 OEM 2.0A "Adaptive Quick Charge" charging block (model Samsung EP-TA20JWE) sitting around - which works with Qualcomm Quick Charge 2.0 Technology.When using this Samsung OEM charging block to power the Nighthawk in the same setup as above, I have not experienced any Nighthawk reboots in about 30 minutes of testing. For good measure, during the video streaming, I added the following (all concurrent):- turn on the Nighthawk's LCD screen on in full brightness- powered on both the 5ghz AND 2.4ghz radios (one device connected on 2.4ghz, two devices connected on 5ghz)- ran speed tests Notes:When logged in, under the Settings|Diagnostics page, I see that the:o charging is detected as "QuickCharge"o the temperature shoots from about 33 degrees Celcius (when Nighthawk is realively idle) to 50 degrees Celcius during my testingOne question I do have is how does this Samsung 2.0A charger differ from the NIghthawk's included 2.0A charger ? An amp is an amp is an amp, so why does using the Netgear-provided 2.0A charger result in the reboots but using the Samsung OEM 2.0A charger work perfectly?

Runnning without a battery requires a charger compatible with Quick Charge 2.0 and that provides 2.4A of output. The charger included with the hotspot doesn't meet those requirements.

winger13: When I started running the M1 without battery using my upgraded charger the temperature range rose to between 36degC and 41degC, rising to the latter with more networking activity. I removed the battery cover and raised the M1 a few centimeters off the surface to allow air flow around the battery compartment. I also carefully placed an old CPU heat sink on top of the M1 with some cling film between to avoid damage to the LCD screen. This approach dropped the M1's temperature range by 5degC (31degC - 36degC). As you wrote in your message 18 above, the recommended operating temperature range is up to 35degC, so I'm only 1 degree over. You could use a fan but I didn't want the constant noise - my M1's in a living area.

winger13: Here it is, with an Intel CPU heatsink on top. I didn't bother connecting the fan because the temperature is fine without it, so there's no added noise. I used the clamp from the heatsink underneath the M1 to raise it - fits a treat! You can also see the short pigtail adapters to convert the TS-9 external antenna connectors to the SMA connectors from my Poynting antenna. I used pigtails rather than a solid adapter like this because I felt that the M1's TS-9 connectors would be put under more stress by the latter. Other connections are Ethernet (to unmanaged switch and 2 access points) and high-quality, braided USB-C cable to upgraded mains charger.Intel CPU heatsink on Nighthawk M1

  Hi All,
  
  Not sure it helps anyone, but here is my feedback. I have tried the above settings and I have definitely gotten some improvement. I definitely regret updating the firmware as it was perfectly fine.
  
  I have actually bring down the screen brightness as well, just so that i can bring down the temperature. From that i got longer usage.
  
  But what i suspect here is that if the temperature keeps going beyong 41 deg, it will reboot and not allow you to start till it cools down. but what i did was just taking out the battery and inserted in back again.
  
  Any idea, where or how i can get hold of the older firmwares? i really want to flash it manually as I could see from my admin page that i can upload firmware and restore it.
  
  Thanks!

    I ran my tests which shot the temperature to 50 degrees Celcius and the Nighthawk continued functioning (no reboots)
