R7800 drops internet connection on ethernet cabled connection (not on wifi)

Hello again. I'm back, and that means so is the internet drop-out on the ethernet connected devices on my R7800 router.

I had the first drop-out last Sunday, April 5th at 8h30 PM, lasting for about 1 hour. Then the internet came back, only to drop out again around 10h00 PM. Then I gave up.

As you suggested in a previous post, I tested to see if the issue occurs when I connect a pc wired to the modem/router from my ISP. So when the drop out started at 8h30 PM on Sunday, I wired my laptop to the ISP router: internet connection OK. When I wired it to the Netgear R7800: no internet. When I put the laptop on wifi on the R7800: internet connection OK (just as it had been before during these wired drop-outs).

On Monday, April 6th, there was no drop of the wired internet connect at 8h30 PM (or at any other time during the day).

On Tuesday, April 7th at 8h30 PM, the same thing happened as 2 days before, although I did not monitor how long it lasted. I gave up and watched some TV.

I am curious about what will happen tonight or tomorrow at 8h30 PM to see if there is a (2-day ?) pattern to be found.

Do you have any clues as to the origin of these weird wired internet drop-outs?

It could be the way the actiontec is doing IP lease times potentially.

Do you have a static IP address set for the R7800? 

A 2-day pattern might be building because today there was no internet drop-out at 8:30 PM.

I don't understand what the actiontec is, but I don't have any static IP adresses assigned (not for the R7800 router, nor for any other device linked to it).

I checked the "Static routes" on the Advanced Settings of the R7800, and there were none (see screen clip attached). On the Advanced Home tab, the LAN port has DHCP = on.

sorry, meant the bbox router you use. It might have lease times and need the R7800 to be set with a static ip address within the bbox

I only have limited access logging in as a normal "user" to the bbox. I cannot see anything about static or dynamic IP adresses nor on lease times. I cannot login as an "admin" or as an "expert" user with the password printed on the backside of the bbox (ISP router).

I did check the IP adresses several times over the period this issue has been going on, and the R7800 always remains on IP adress 192.168.1.2, just like my NAS always stays on 192.168.1.6., even after restarting both devices (R7800 and bbox).

If the lease times would be the problem, then why would it only be causing trouble on the internet connection of the wired devices to the R7800 and not on the wi-fi connected devices?

I attached a screenshot from the bbox GUI indicating that the bbox clearly recognizes the R7800 as an access point.

I did a little search on Google and found out that I am able to see the DHCP lease is enabled in the bbox ISP router. See screen clipping attached.

At the same place in the GUI of the bbox router, it seems I would be able to assign static IP adresses (see screen clipping attached). Would it also help if I put a longer lease time in stead of the current 3600 seconds? This is a home situation so generally, it is always the same devices that are connecting.

Thanks again for your advice!

You could try changing the lease time. If its 3600 minutes, thats 60 hours or 2.5 days. 

You can leave it at 3600, that's a standard default.

So, you said earlier that the NAS and the Printer were hardwired to the router.

So, they are hardwired to the bbox and are not associated with the R7800 AP at all, correct?

additude:

The NAS and the Printer are hardwired to the Netgear R7800 router (which is used as an Access Point). They are not hardwired to the bbox. The only hardwired device on the bbox (ISP modem router) is indeed the Netgear R7800 router. All other devices are connected (hardwired or wireless) to the R7800. The wi-fi on the bbox is turned off.

plemans:

I think the lease time (3600) is in seconds not in minutes (I believe). But since additude says, it should not make a difference, I don't know whether to change it or not.

By the way: I was expecting an internet drop-out yesterday (April 9) at 8h30 PM in the 2-day drop-out-schedule that was building up. But no, nothing happened. The internet stayed available.

OK,

For the sake of this conversation, please refer to the modem/router as the "Router" and the R7800 router turned AP, "AP" or "Access Point"...

In your first post you said, "I also have a Synology NAS and a HP printer connected to the router on ethernet ports."

How is the cable between the bbox and the AP connected? LAN to LAN? LAN to WAN?

Hi there. I checked the wired connection between the bbox router and the R7800 AP.

On the bbox router, the ethernet cable is in a LAN-port (not in the WAN-port).

On the R7800 AP, the ethernet cable coming from the bbox router is in the port labeled "Internet" (next to the 4 LAN-ports labeled 1 to 4).

Hi moopig.

Thanks for your reply. It finally seems that I am not the only one suffering from this weird behavior on the R7800.

The internet drop-out on the ethernet cabled devices still occurs every 2 or 3 days days, difficult to find the correct pattern since I am not always using these devices when it occurs (at 8h30 pm).

So I still have not found a way to make 1.0.2.68 work reliably in AP mode with wired connections. I do not remember when this firmware was installed (upgrades were installing automatically).

Instead, I reverted just now (April 27, 8h05 AM Belgian time) to the previous firmware V1.0.2.62 hoping it will solve the problem. If that worked for you, I am praying it will also work for me.

To be safe, I have turned off the automatic router firmware update. I did not perform a factory reset after reverting to V1.0.2.62.

Now I am keeping my fingers crossed.

Hi @moopig.

As stated in my previous reply, I reverted to the previous firmware V1.0.2.62 on April 27th (8h05 AM Belgian time) hoping it would solve the problem. And IT DID !

Since then, I did not experience any internet drop outs on the ethernet wired devices to R7800 (at least not during daytime - I don't have any tools to monitor if it would happen at night when nobody is using these devices).

Thanks again for your valuable reply!
