R7800 drops internet connection on ethernet cabled connection (not on wifi)
I've been experiencing this problem for several months now and it is most annoying.
Every day at the exact same time (17h27 and 20h34 and some days also at 13h45), the router R7800 drops the internet connection on the ethernet cabled pc's, for about one hour.
When I take the cable out of the ethernet slot and put the pc on wi-fi, then the internet is working on wi-fi on that same pc. The wi-fi is providing internet connection to all my wirelessly connected devices during those time slots (such as smartphones and a Surface tablet).
At first I thought is was a problem of some job running on my main pc, but the same problem occurs on my laptop when I connect it with an ethernet cabel to the router.
The router has the latest firmware and I have done a reset to factory status and restarted it multiple times, without any solution to the problem.
I also have a Synology NAS and a HP printer connected to the router on ethernet ports. During the internet block time, the pc can still reach the NAS and the printer, so it seems only internet is locked down.
What is going on here?
Thanks for your help.
Hi Filip_Serlet.
I had a similar problem with my R7800 in January.
Like you, I am not using my R7800 in the usual router mode. I have mine set up as a wireless bridge, not as an access point. Every few days all the wired Ethernet devices connected to the R7800 would report that they no longer had a network connection. However, the 5GHz wifi link from the R7800 to the modem/router would always remain up when this happened and I could still connect to the R7800's admin web interface across the LAN. The only way I could get the disconnected wired devices back on the network was to power cycle the R7800.
My problems started immediately after I updated to firmware 1.0.2.68. A factory reset can sometimes fix problems after a firmware update but it didn't fix this. Eventually I gave up and reverted to firmware 1.0.2.62 and everything has been fine again since then.
It's been a couple of weeks since your previous post. Have you found a way to make 1.0.2.68 work reliably in AP mode with wired connections?

What actual firmware on you on? A number. "the latest" changes or might not be the latest
What modem are you connected to?
Have you tried a factory reset and re-install? if its been going on for a while, maybe it was caused by a firmware upgrade. anytime there's an issue after a firmware upgrade, a factory reset and manual re-install can help. (not from backup).
Thanks for your reply.
Currently, the router is running on system software V1.0.2.68. I am using is as an Access Point.
The modem is from a Belgian internet provider (Proximus), country where I live. I found this reference on the label: "Sagemcom Modem ADSL/VDSL2/TV PSTN b-box 3V+" and also "P/N: 253670439".
I will do as you suggest: restore to factory settings and restart again. Then update to the latest firmware (mentioned above).
Then I will have to wait a day to see if the internet gets blocked again. I will send feedback on the progress tomorrow (in Belgium it is now 15h00).
Result of reset to factory settings.
So I did a reset to factory settings using the Netgear interface. I noticed that the router remained on the current firmware version V1.0.2.68 (it did not return to the initial firmware at purchase).
Unfortunately, this did not solve the problem. Yesterday at Belgian time 16h55, the internet connection on the wired pc was blocked again as before. So I switched it to wi-fi for the rest of the day.
I also had some trouble with the wi-fi af few minutes afterwards (but not related to the wired internet blocking problem), so I had to restart the router.
You can find the router loggings here below starting from that restart.
Every 30 minutes, and sometimes every 90 or 120 minutes, there is a statement "internet connected". Could this have something to do with the timeframes where the internet is being blocked on the wired machines? I will try to monitor this today.
I have also seen that a lot of functions in the router GUI are disabled, and cannot be enabled. E.g. Traffic Meter, UPnp and IPv6 in the Advanced Settings.
