R8500 frequent self reboot

Firmware: v.1.0.2.80_1.0.71

 

New unit at the end of September (replacing a unit which completely locked up after two months).   The new unit has been working well up until now and then without reason has started auto-rebooting every 10 to 40 minutes.  Tried a reset but has not cleared the problem.  So unreliable I have disconnected it and gone back to the old faithful (but slow) Netgear D6300.  Any ideas.

Re: R8500 frequent self reboot

Thanks for coming back on this.  I had done a reset, but was more than happy to do it again.  I noticed that there is a firmware release today so included that after todays reset.  In the first hour of testing it has rebooted three times.  Really disappointing with the router's reliability.  Two units failed in four months for different reasons.  Will call MyNetgear Support

Re: R8500 frequent self reboot

Mine started doing the rebooting also.  It was working well beforehand.  It started doing the rebooting sometime this AM.  I did see that it had an available update to firmware so I did the upgrade.  This did not fix the problem.  I have the AD Ethernet inputs disabled for the AD.   I'm not sure what the problem is.  It is hard to belive that yours and mine just decided to become defective around the same time.

Re: R8500 frequent self reboot

I previoulsy posted above that my R8500 was having the same rebooting problem.  It seems to have self resolved.  The problem started the evening my daughter and son-in-law arrived and signed-in to the router's guest account.  

 

The son-in-law used his iPad and iPhone.  When he signed-in the connection was rapid.  However my daughter with her Samsung S-4 when signing-in had problems in her phone making a connection with the router.  The phone eventually made the connection to the router.  Shortly there after is when the router began to spontaneoulsy reboot.  The three devices all used the same primary 5G Guest connection.  the 2nd 5G channel is disabled.

 

 The son-in-law and my daughter left yesterday moring.  I noticed that after their depature the router stopped spontaneoulsy rebooting.  The router is again stable.

 

Any experts out there have any theory about the circumstances of this router spontaneoulsy rebooting?

Re: R8500 frequent self reboot

I will certainly be interested to hear if there is an explanation to your self healing router.

 

I don't use any Guest connections, but there are other similarities.  I use the first 5G channel for an iPad and Samsung S-4 and the second 5G channel for a MacBook Pro.  I have an iMac hardwired to the router.  I only connect the phone to the router wifi for updating the apps.  Much quicker than using the 4G network.  Other than then the phone wifi is disabled.

 

Unfortunately my router has not self healed.

Re: R8500 frequent self reboot

What Mfr ISP modem and model do you have?

 

What wireless modes do you have set up on the r8500?

What channels are you using?

Any wifi neighbors near by? how many and what channels are they using?

 

Where is the r8500 place in your building? Next to anything?

Besure all LAN cables are in good working condition and recommend using CAT6 LAN cableing.

Re: R8500 frequent self reboot

-What Mfr ISP modem and model do you have?

Cisco DPC3208 (Broadband)

 

-What wireless modes do you have set up on the R8500? What channels are you using?

2.4GHz b/g/n is enabled Auto channel (never conflicts with neighbors) Mode up to 1000 Mbps WPA2-PAS [AES]

5GHz a/n/ac (Smart Connect – One wireless network for both 5GHz radios) Channel 44 (no neighbors using this frequency) Mode up to 2165 Mbps WPA2-PSK [AES] 5GHz-2 Channel 153 (no neighbors using this frequency) -Guest Network 2.4GHz b/g/n, 5GHz a/n/ac (5GHz is disabled)

 

-Any Wi-Fi neighbors nearby? How many and what channels are they using?

Four neighbors, one behind, one just to left and two across the street. Signals on a good day are 1 to 2 bar. They use 2.4GHz b/g/n. I’ve only seen them on channels; 3, 6, 9, 11.

 

-Where is the R8500 placed in your building? Next to anything?

This is a two story house. The R8500 is atop a tower in the living room. Nothing is next to it. It has four Cat 6 Ethernet cables connected to ports 3 – 6 (1 & 2 not used) where two terminate at D-Link DGS-2208 switch, one terminates at a D-Link DGS2205 switch and the last Ethernet cables terminates at my Brother MFC-5895CW printer.

 

-Be sure all LAN cables are in good working condition and recommend using CAT6 LAN cabling. CAT 6 Ethernet cables in excellent working order.

The R8500 router is still working flawlessly since the daughter and her husband left with their devices. So FURRYNUTZ with this information, what do you deduce?

 Checking for NAT here is all. Thank you.

2.4GHz b/g/n is enabled Auto channel (never conflicts with neighbors) Mode up to 1000 Mbps WPA2-PAS [AES]

Can you try switching to mixed G and N mode or single mode N if you don't need B or G mode?

 

5GHz a/n/ac (Smart Connect – One wireless network for both 5GHz radios) Channel 44 (no neighbors using this frequency) Mode up to 2165 Mbps WPA2-PSK [AES] 5GHz-2 Channel 153 (no neighbors using this frequency) -Guest Network 2.4GHz b/g/n, 5GHz a/n/ac (5GHz is disabled)

 Can you try switching to mixed N and AC mode or single mode N or AC as a test? Disable Smart Connect and manually set modes.

Are you using both radios? Test with one of the 5ghz radios OFF.

 

-Any Wi-Fi neighbors nearby? How many and what channels are they using?

Four neighbors, one behind, one just to left and two across the street. Signals on a good day are 1 to 2 bar. They use 2.4GHz b/g/n. I’ve only seen them on channels; 3, 6, 9, 11.

 Try manually setting channel 1 on 2.4Ghz.

Another test to try would be to turn OFF the wifi radios and see if the router still reboots on it's own with them OFF.

This is a two story house. The R8500 is atop a tower in the living room. Nothing is next to it.

 You might disconnect these switches when you can get some time to rule out any thing coming from the switches. Find out if the router still reboots with out them being conected.

Hoping with some suggestions might be able to narrow it down more.

Re: R8500 frequent self reboot

I think that the next time my daughter and her husband return with their devices and the problem crops back up then, I'll try narrowing down the problem.  Can't narrow anything down with the R8500 working flawlessly at this time.

 

Also making the canges as you suggest to troubleshoot for fixing the problem should not be necessary when using this router.  If these adjustments are requried to keep it from spontaneously rebooting, then the router is nothing more than a boat anchor, which is not the case.

Re: R8500 frequent self reboot

Don't be so quick to judge the suggestions. These are meant to help you trouble shoot. Also some for optimal operation as well.

 

If the problems went away after your family left, then I might think something they had connected and or were doing while visiting maybe the cause.

Re: R8500 frequent self reboot

Not judging, good suggestions. I think that it was the Samsung S-4 phone connected to Wi-Fi that was causing some type of negative interference triggering the reboots.  If the problem returns, I'll do the troubleshooting suggestions you have provided.  I had done quite a bit of troubleshooting when the problem was happening.  Of the troubleshooting, I didn't chang the two 5G channels back to separate, thinking that the guest access was more or less isolated from the rest of the system.

 

I'm of the opinion that others who experience these annoying and aggravating spontaneous reboots just may have a device that is causing the problem more so than the router being defective.  However, there are duds with any given manufactured devices, sometime in batches

Re: R8500 frequent self reboot

I've seen Samsung phone issues before.

 

You'll have to check it out again if they return.

 

Good Luck.

Re: R8500 frequent self reboot

Maybe your router is faulty. Same symptom like mine.

Just for your info there are 2 version of Netgear R8500 (good one is with BLUE WAVE LINE on TOP)

 

My previous (1st version)  is with total wave black on top

https://www.cnet.com/products/netgear-r8500-nighthawk-x8-ac5300-smart-wifi-router/ (version 1)

 

 

2nd version (with BLUE WAVE LINE on TOP) which is good one!

http://gadgetynews.com/netgear-nighthawk-x8-r8500-router-review/ (version 2) 

 

Now problem gone, solid router!

Re: R8500 frequent self reboot

The router I have has the blue wavy line, so the better model.

 

After many reboots I contacted Netgear and they asked me to go through all the reset processes again. I don't believe I did anything different while "under instruction".  I had boxed the unit up ready to be returned so it had been out of use for a number of days.  After the phone call it has self rebooted a couple of times, but generally seems more stable.  One thing I now do is to switch the unit off each night.  There has been a number of comments elsewhere about overheating, so this gives it an opportunity to cool.  Whether this has made any real difference I don't know.  All I can say is that it is stable enough not to be a concern.  Just hoping it stays that way.

 

The Netgear person I spoke to did say that if it causes any further problem then I should return it for a replacement.
