Posted: Mon Sep 23, 2024 8:21 Post subject: I feel defeated [SOLVED]
First and foremost I would like to say great job to all those that keep this forum going. I have been for a few years reading howtos from google search on dd-wrt com. Up till it has fulfilled my needs. Please take into account that my knowledge is purely of what I have read and playing around with router settings. I am by no means a professional and thus have hit a wall that for the last few days (yes days as I have spent hours) reading and trying to figure it out by myself but to no avail) Therefore I need some help and guidance from the community. I have searched wide and far and maybe i missed it or using wrong search criteria, yet everything I have read and tried, does not work. To the masters, it most probably will be a straight forward problem. I will try to include all info I can.
What I am trying to achieve?
ISP to Netgear with VPN. I want all connected devices to go through my AC1700. So the AC1700 dishes out all ips within its network. ISP subnet is 192.168.0.x.... I have set up AC1700 subnet as 192.168.1.x. So technically the ISP is simply the internet connection to my AC1700 router/modem. That is why i have DHCP on in AC1700.
How have I set it up?
From ISP modem to AC7000 WAN port. I have set static ip as ISP modem has very limited options.
So on ISP modem I have set the given ip to router to go through DMZ.
And then on AC7000 also set the same ip as an static ip. AC1700 is set as Gateway.
The problem?
Everything works just fine,including VPN but all of a sudden I loose all internet access. Most times I cant even gain access to AC7000 (wired or wifi). When I cant gain access to AC7000, it seems I loose gateway information. I will have to reboot AC7000 and it will work well again for some time. It can go hours with no problem or every few minutes doing it. Problem seems to come and go. Yet it has not worked as it should for a whole day.
Have I set it up wrong as per fotos?
Any help to actually solve this is highly appreciated. I am tired and really feeling defeated. Maybe I have to take another approach to it but Im lost right now.

Thanks for the taking the time to help and give some advice.
Like I said, everything I know about routers and networking was learned over time by reading and videos and trying to figure it out by my self. It is a very complex world and not easy for ppl like me.
Last night after arriving from work, I followed your advice and did a fresh install and configured it over again by hand and behold....It has not lost connection once till now. Normally each morning, I would have to restart router to get internet access again and then a couple of times again before going to work.
Just a quick question...I read different "opinions and suggestions" about the resetting NVRAM.
If I understood correctly, in my case, by using the reset button on router clears the NVRAM to default correct? So there is no need to SSH command into router.
Or is it still recommended that first clear NVRAM then proceed to clean install?
Once again thanks for your time
Highly appreciated.

Resetting to defaults from the GUI is fine.
No need to do "nvram erase" from the command line.
The only more serious resetting is erasing the whole nvram partition ("erase nvram", followed by power down) but that is dangerous as it can brick some routers (not yours) so not recommended.
I will have to reboot AC7000 and it will work well again for some time. It can go hours with no problem or every few minutes doing it. Problem seems to come and go.
I came across this post on our way to visit my sis-in-law 2 weeks ago, whom I'd just heard from the wife was having internet issues (Spectrum) w/ the EA6900 (w/ Xvortex CFE) I set up in May. It was fine last I'd heard (~July), and the wife was down there a few weeks prior and had no problems. But then I hear "its been not working for weeks". Reboot fixes it for a few minutes or few hours, then quits again. I noticed it would connect but show 'no internet' and browsers would show DNS issues.

Under Network setup, please keep Gateway and Local DNS at its default settings 0.0.0.0 which means automatic!
Either disable Shortcut forwarding engine and Flow Acceleration or use CTF and FA for flow acceleration
This caught my attention, because I previously set this up as an AP but when I switched back to GW, I did not recall changing the 'Gateway' and 'Local DNS' back to 0's...which I indeed found. /facepaw ...and it was set for SFE. So I changed those and it worked fine all weekend; until the wife and I were literally walking out the door to leave on Sunday. No internet, even after a reboot; the WAN was connected, but not talking to the internet.

I did a reset (don't recall if GUI or button), but same issue, so I swapped her router to the backup ZyXel AC2200 (OEM OpenWRT-based) to bring the EA6900 home for investigation. She's had zero issues since.
I had also been unable to update the EA6900 until egc's reply, but got it w/ the CFE webserver. After getting back from vacation a few days ago, I set it up as my gateway for testing, but still no WAN (Comcast). Everything looked right; had a WAN IPv4, DNS address, etc. - but no internet, and DD didn't get NTP time either. Reset again, same thing. Connecting to the modem worked fine.

So I telnet'd in and did an 'nvram erase' and 'erase nvram' (didn't want to spend 30sec searching which was correct now) and voila - internet instantly came up, and I've been running it as my GW for 3 days now without issue. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#
