DNS issue appears after 8-12 hours of AOT-4221SR router runtime - Restarting fixes the problem temporarily

You can specifically ask the engineer to change your ONT device to a different model. See if that helps.

@doineedto, I had an engineer show up and, I replaced my Sercomm AOT-4221SR router with a Nokia G2425GA router but even that router becomes unresponsive after a period of 4 to 6 hours of runtime. Of course, a restart makes the router responsive but that is a workaround - like I have mentioned before.

@t0xic0der what do you mean by unresponsive? Have you tried manually adding DNS on the OS level?

The pages that I have visited before like Google etc load just as fast as they did before - and I suspect that is because of the responses being cached while if I were to load some other website, the browser would go on to load them forever and then eventually timeout. On refreshing the pages where the timeout occurred, I refresh the page and this time around they load up but they have broken assets, links, images etc. I even try to access the router admin page but to no avail, as even that keeps on loading forever and then eventually times out. Mind you, I ping the router's admin page but it gives me very inconsistent ping delays - noting that something is not right. That is how I would describe unresponsive here.

off topic: Why did @nishantt6969 get banned?

I do not know but the guy was really helpful to not just me but a bunch of people around. A bunch of his comments were really useful to me back when I was simply a lurker and I do not see why he would get banned. @moderator, can you please help us understand the same?

@t0xic0der better use ur own router … and aot use as a dumb ont …

I want to do it but I think that setting up a bridge mode requires me to have a public IP address. Correct me if I am mistaken here.

only aot ont is unlocked …

A bunch of settings on my Sercomm AOT-4221SR router were greyed out so I do not think it was unlocked.

@albonycal when posts are this long. people tend to skip :D

Also, the question arises from where he turned off IPV6 whether from the router or the device. I would suggest turning off from router means just dialing IPV4 PPPoE.
 
@Lolita_Magnum, hi there - from the thread here, Is it worth using bridge mode for Airtel Fiber. | Airtel Xstream Broadband - I found you mentioning this

It also seems that the router might not powerful enough when more devices are communicating in the subnet.

I happen to have around 12 devices (6 of which are virtual machines) and 6 of them being either mobile phones, laptop computers, desktop computers, smart TV etc. I would be interested to know how which router you used there and how you figured out that the performance was degrading as I suspect I might be facing a similar issue here.

I have like 40+ devices, operating over 5 subnets, i.e., 3 /29 and 2 /27.

Currently, I am using an Archer A6v3 (bought 2–3 years ago).
It is good enough for my use case, which includes, 2 failover WAN profiles, routing the subnets above, 3 point-to-point VPN running BGP across.
In NAT-mode, the device can easily touch 1Gbps over WAN due to the presence of hardware acceleration.

I use a separate device for Wi-Fi, and any inter-LAN communication is via a POE Switch by Netgear.

If you want to use Stock OS and still want something a bit of power but reasonable, C80 and AX10 are also a decent choice.
I don't recommend D-Link anymore due to bad blood and if you are looking for the expensive sector then I am sure the forum is full of recommendation.
