I usually only upgrade my Netgear R7000 once or twice every year. My last install was from May and was super stable and working perfectly even 100 days without reboot. I did a reset and flashed Kong's latest (3 december) and are having very weird issues regarding wifi. Every now and then the speed (when doing speedtest) is reduced to 0.5 Mbit/s. However if I turn off and on the wifi on the client (phone for example) I got my 100 Mbit/s back again, for a little while. Mind you that I would still have a "Excellent" connection to the network, its just the speed that is reduced.
It seems to me that wifi has gotten very unstable and maybe more specifically, the radios.
Is this the famous VAP bug I have encountered? I have read a little about it but I don't understand its consequences.
Have you erased NVRAM and put settings in manually?
The VAP bug only has an effect on a VAP besides Kong has gone back to different drivers in the 37900 build which should be better.
in the build thread there is no one else reporting this (yet, which does not mean it is not real and maybe a bug )
Alright, no I just used the Reset option when updating firmware in the UI. I will do a NVRAM reset tonight and try again and report back.
@Kong thanks for this, I tried both not long ago and both were resetting to default.
Correct me if I am wrong but does "erase nvram" not erases the nvram partition?
Which although resets but is not safe to use on all routers.
And what does "nvram erase" do? Is it just iterating through all the nvram parameters and set them to ""?
Is this safe to use on all routers?
How did you verify, that nvram was erased?
If you call erase nvram then nvram mtd gets erased, but on reboot or any other action nvram is saved to mtd from ram. Thus unless you power off via button right after you called erase nvram you have not cleared anything. nvram erase however clears nvram in ram and then writes to flash. _________________ KONG PB's: http://www.desipro.de/ddwrt/

root@R6400v2:~# erase nvram
Flash is NAND
On reboot my settings where all gone and the router starts with asking for username/password, so that leds me to the conclusion that nvram was erased, but I did not check all nvram parameters.
No only some of your settings where gone, the ones that don't get read very often. In RAM there is a certain amount of reserved space for nvram vars/keys, when reads/writes occur, they get cached and flushed out when a commit is called, e.g. reboot now calls a commit. That's also the reason why you have to call a commit to make a setting permananent:-) _________________ KONG PB's: http://www.desipro.de/ddwrt/

Kong is it on all the routers or only those you support?
