In the gui under Administration on the Restore/Save/Upload settings tab, select Restore to factory defaults.

Resetting to factory settings clears the NVRAM. Check your wireless adapters for issues. See if they have the latest drivers installed on them.

my friend had a similar issue and he cleared his nvram and it got fixed but it was on some other router tho he did some command like mtd-erase -d btw my wireless adapter dont have any issues and i 3 wired connection and 3 wireless i tried just using wired connection only but still drops connection and sometimes speed goes down so yeah

 

[CrYz]

and does both hard reset and the on gui reset NVRAM? and hard reset is holding red button on router for 30sec right?

 

[sm00thpapa]

Factory re-set, hold reset button for 10 seconds and release or hold the wps button while you plug it in till the light blinks and release will reset all to factory settings. If your hard wired devices are dropping connections I would consider returning the router.

I am CONVINCED there is a problem with fully resetting this router. I'm NOT convinced ANY of the methods work reliably. Of course they work for most people most of the time, but if you are unlucky and your router gets in an odd state.....There are a number of people, me included, who have had weird unique problems (mine involved br0 looping errors since 4825 visible in the log and disabling the network that would only happen if the 5Ghz guest network was enabled), that have not been solved with multiple resets.

My problem eventually magically vanished when, more in desperation than anything, I put the final release 4950 on top of the IDENTICAL (we did a file compare) beta 4950! So, I would try that - resetting, installing identical firmware over the top of itself and resetting again afterwards and/or just using all reset methods together. Hopefully, eventually, it will work.

I always use this command after flashing to wipe nvram:
mtd-erase2 nvram
Then I power cycle the router

Login with telnet or ssh client (i.e. putty)

I wouldn't like to contribute to brick your router. You'd better stick to the Web UI or WPS/reset buttons methods.

plz tell me how it doesnt matter if i brick my router plzzzzzzzzzzzzz

OK, that's the attitude I like, I mean: If it ain't broke then it needs more tweaking
It's very simple:

1. First of all you need to enable Telnet login from Web UI:

2. Open a command prompt (I must assume you already know how to do it, otherwise you'll find billions of thousaunds of guides)...then execute telnet:

telnet [your router ip]

It will ask you user and passwd...

Then you are already into your router's shell.

3. Now i'ts time to wipe the nvram, just type this:

mtd-erase2 nvram

Note: This command is valid for AC68U, AC87U and later models.

Now your router's nvram is blank.

4. The last step is to power cyle the router. Shut it down. Wait from 5 to 10 seconds then power it on.

Now it will boot with 101% granted nvram wiped out.

Unless you can guarantee 102% I'm not risking it.

telnet is no longer installed by default starting with Windows Vista. You must either add it through Program & Functionalities, or use a free client such as Putty or XShell.
