Custom firmware build for R7800 v. 1.0.2.63SF

[NetBytes]

Hello Voxel. Thank you for your efforts. In December I got a new 7800 and had the 5GHz dropping issue with the stock firmware.
I found this site and your firmware, applied 62SF and ran perfectly for the past month.

Last night I applied 63SF and when my router rebooted it would/could not connect to the internet, everything else was fine/correct.
Wan connection was dead and every value for it was zero (ip addr, dns, etc).
I re-applied 62SF and had to hard-reset the router as the admin password was scrambled and the
admin recovery page always told me no good even though I am sure everything was correct.

With the downgrade and hard reset complete I can easily re-configure back to a working "62SF" router.
I tried to upgrade to 63SF a second time and same results.

It looks to me 63SF completely loads/updates into the router, but once it reboots the WAN connection is dead.
Connected to cable modem: 62SF immediately connects, 63SF never connects.

Any ideas?

HT160 could affect range and cause some instability in comparison to having it disabled in my personal experience, yes.

If you don't know anything about wireless technology, I'm going to hazard a guess that you have no use for HT160 and very likely don't have a compatible wireless device to utilize this feature. I would disable it.

haven't had any issues since disabling so i guess that was my issue. guess i'll just leave this here in case anyone is googling in the future and runs into issues with their 5ghz radio going down during downloads while ht160 is enabled

but the bufferbloat is the same. B on dslreports..
How can I improve?


PS: came back to 1.0.2.63SF..

Well. It is very strange of course. I cannot say what is a reason. Don' t you have to use a password for your WAN connection?

Did not you try to check just a stock 1.0.2.62? Also now you had to reset your router when it was flashed by 1.0.2.62SF. But it has a sense to perform reset when you are with 1.0.2.63SF.

Unfortunately bufferbloat might happen somewhere on the way from your router to the target site. E.g. your modem. Not because of router...

Did not you try to limit the speed (QoS)?

I tried various versions of congestion control (I have no idea which is best for my connection - or what the differences are), I also tried changing the wmem and rmem max values

I have 50Mbps down, and 11Mbps (measured). I set my QoS speed settings to 48.5Mb and 8.5Mb to manage.

Sometimes on the test it made no difference, other times it lowered the bufferbloat but decreased the quality so I just left everything at default and accepted a C bufferbloat result.

In reality, all of my online gaming works fine with QoS setup, with the PS4 set to highest priority.

I should have been more clear. Is there a boot log file i can check, or some debug options I can enable to see why the 63SF
fails to connect to my ISP? The connection is a standard DHCP connect, no password or special setup - only requirement is router's mac address (can't imagine that changing because of firmware version).

Some times you have to turn the modem off for 2-3 minutes as well. Router off, modem off. Then turn modem on, let it sync and then the router.

I tried to enable dnscrypt v2 while keeping OpenDNS as my DNS provider.

I enabled it, commited it to nvram, edited the dnscrypt-proxy-2.toml to only use 'cisco' in the server_names, and rebooted. After the router rebooted, I lost all DNS. I sshedback in, disabled it, and rebooted to DNS working again. What did I screw up?

I think there are no major differences between the tcp algorithms for congestion control (as regards cubic and yeah). Maybe cubic is more stable in all conditions and yeah more performing but it is a question of impressions seeing the various dslreports charts.
Big improvements can be made by lowering a lot the maximum band down / up in QOS. But in this way there is a loss of the capacity of your line..
I think the best management of the packets is in the firmware LEDE that has no important NG proprietary features..
Anyway I managed to get A in the dslreport test only 3 times after many tests. Perhaps randomness or perhaps the very low QOS limit.

Voxel, i am having this exact same issue except once i unplug my modem and plug it back in everything works. My ISP does not have a login or password my ISP is comcast

Do you mean you are unplugging the power to the cable modem to force it to reboot?

Hello,
I did not update my R7800 for a longer time. Now I have installed the 1.0.2.63SF and something seems to be broken with ReadyCloud.
http://readycloud.netgear.com shows my router but not the connected Hdd.
In the WI of the R7800 readycloud is still registered. When I click unregister, the R7800 seems to unregister, but when I reload the WI it is still registered.
Is there anything else I can do before I have to restore default settings? Does anybody have this issue, too?

What browser are you using? Try IE11 or FF or Opera and seen if you can un-register.

Not sure why anyone would complain about him, his releases are better than the stock firmware. Since I do not have a very fast connection, I don't really do anything that will stress the WAN to LAN connectivity, but areas of great improvement for me has been the storage performance for both eSATA and USB 3.0, compared to the stock. VPN also has had improved performance.

I prefer releases like this to massively different firmware such as DD-WRT, Tomato, and many others which while they often have advantages in the responsiveness of the UI and many more features (of which virtually all have a nice user friendly GUI), they tend to benchmark lower across the board when it comes other router functions. This is a strange departure, especially compared to the days of routers like the wrt54g where switching to tomato not only got you a more responsive UI, but also better networking performance.

It seems like with more modern routers, the companies have put more effort into optimizing things in ways that do not translate to completely different firmware that may not have access to such code, but the hybrid approach of Voxel seems to give us the best of both worlds.

The DD-WRT/Tomato approach is to start from scratch and use open-source drivers that do not have the manufacturers proprietary performance enhancements. The benefit is to have extra features but the cost is less overall performance. Both Voxel and Merlin (for Asus) keep the manufacturers closed-source drivers while improving the open-source code where they can.

Its not an browser issue. I have tried it with different browsers on different computers. I thought there would be somewhere a config file for readycloud i could delete...

Probably problem is on the side of your modem as proved by other guys...

edited the dnscrypt-proxy-2.toml to only use 'cisco' in the server_names, and rebooted

Sorry, I did not check 'cisco', maybe problem is on their side. Did not you try other Cisco servers like e.g. cisco-familyshield?

I checked this right after I flashed my 63SF on my router. I was able to see my files. And register/unregister. Regarding register/unregister: now it is stored in nvram in encrypted form. Maybe because of this. Probably

I did not update my R7800 for a longer time.

is a problem and it would be good to perform intermediate update to say 1.0.2.62SF. BTW, what was your previous version: my or stock?
