X4S R7800 Firmware issues ISP IP drops

For the past year at least my ISP network will drop.  I will still connect on the WiFi bands (2.4 and 5Ghz).  However, I will lose my ISP network.

I initally tried to just reboot the cable modem (Arris brand from ISP).  That used to work, however.  When I rebooted the router, it wouldn't work. I wouldn't get back my IP address.  Even if I waited for 10 minutes after a reboot.  It wouldn't get a new IP.  Release/Renew didn't work either.  If I disconnected the CAT5e cable on the router that goes to the modem.  And then reconnect, it would get a new IP.  No other way would it receive it.  I'm begining to think that either my firmware is not working well OR my connection/PORT is somehow bad.  This happens at least once a week now on average.  I just did the beta firmware for V1.0.2.63.  And even after a reboot and firmware update.  The IP will not come back from my ISP.

 

I changed the the CAT5e cable just to make sure that wasn't the issue, but it will still happen about once a week.  Everything looks fine otherwise, but my connection will just drop.  I've read a few similar issues here on the forums but, I'm seeing the issue for several firmwares.  I don't want to go back to far and be unsecure, but I can't deal with this issue anymore either.  This never used to be an issue.  I'd lose a WiFi connection from time to time, but my ISP would never drop like this.  I was starting to blame the ISP before testing as much as I have.  

 

Is there a stable "solid" firmware that doesn't have any issues?  If so, which version is it?

Have you tried a factory reset and reconfigure from scratch?

I have not.  It took some time to configure this the way I want.  Last thing I want to do is reset the whole thing.  

I'm just losing the internet port NIC.  This shouldn't happen.  Firmware updates and reboots haven't helped.  If I have to factory reset it as my only option, I'll need some time to get all that done without affecting everyone in the house.

Ok, so I guess I'm the only person to experience this issue.  

I'm going to do a factory reset, which it looks like I can do from the GUI. I assume it doesn't matter which (button reset or GUI).

If the problem persists after a factory reset.  Then what?

Re: X4S R7800 Firmware issues ISP IP drops

So, I replaced my X4S with the RAX80.  Clean setup, just renamed my wifi to the same that it was, and IP'd it as it was before.  Updated firmware, and that's it.  I did not copy the old config or anything else.  

 

SAME ISSUE.  I drop my internet all the time.

 

So, I said OK, lets replace this cable modem.  Which was all of a year or so old itself.  I replaced it, got it back up and running.  


SAME ISSUE.  I drop my internet all the time.  At least every other day.  I'm connected to my wifi.  OR I am not really connected.  Some devices like my phone will show connected, but other devices will show no ethernet, or they have red lights indicating they are not online.  

 

I don't want to switch brands, I have used Netgear for awhile now, and I can't believe going to a whole new router has not solve my issue.  

I have many netgear products, so I don't get it.  What gives?  Does this not happen to other folks?  Is there any known issue with ARRIS modems and Netgear routers?  Something, anything at this point would be helpful.

I think this has something to do with the very old tools NETGEAR uses. Their DHCP clients udhcp/dnsmasq are very old versions and may cause such problems.

 

A last thing you can try is to put a small, unmanaged Gigabit switch between the router and the modem. Sometimes this is known to work for some people

 

In the end, if I was you, I'll return the RAX80 and go for an ASUS with latest RMerlin firmware (based on stock with RMerlin improvements/bug fixes)
