Hi, I'm wondering how stable Archer C7 v2 with OpenWRT is as a Wi-Fi router.
I have a 200 Mbit connection at home, and I recently purchased a bricked C7 v2 for pennies, which I unbricked the same evening by properly flashing latest OpenWRT 22.03 on it.
I later found out that, just like other routers I had before it, this one is not perfect, as it tends to drop wireless clients. However, while I did initially see a manifestation of this problem in the logs, I didn't really feel the consequences of it, and these entries stopped appearing soon after. But a bit later, I started experiencing some intermittent connectivity issues which I didn't have with my previous routers. E.g., sometimes, a page will take longer than usual to load, or a VirtualBox VM I'm tinkering with will lose Internet connectivity (at least partially), and stuff like that. I was wondering if this is common for this router, or something specific to my case/config (which is pretty much the default).
I tried replacing the
-ct firmware and drivers with their non-ct variants, as suggested in the topmost post here, adding the memory limit fix to
rc.local and disabling LDPC, but I'm not sure if any of these actions had any positive effect. I don't feel like they did.
Also, I ran the bufferbloat test multiple times, and the grades I get on subsequent runs are rather inconsistent, jumping anywhere between A and C (I think?). I normally wouldn't care much about it, but I thought maybe it's related to the occasional lag I'm experiencing. Or is this all because of the unsupported hardware NAT perhaps?
So, all in all, I'm now wondering if I should just re-flash factory firmware and sell the device off, or if it actually has enough juice to perform well as the only Wi-Fi router in a small home on a 200Mbit connection. For now, I've reset it to OpenWRT defaults again, and only made minimal adjustments (enabled Wi-Fi, set the root password, enabled nightly reboot, installed Attended Sysupgrade and upgraded the few packages that had newer versions) to check once again how it works with OpenWRT out of the box.
By the way, why are there two DevDB pages dedicated to C7 (here and here)? Shouldn't they be merged?
