First of all let me tell you am not much expert of such equipment. I have Ea 6900 v1.1 i followed this guide https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=291230#291230 and successfully installed DD-WRT v3.0-r32868 (07/27/17) this firmware. Now Problem is am not able to write cfe as whenever i tried to unlock using [mtd unlock /dev/mtd0] it says cannot unlock and whenever i try to use this command [mtd write -f new-cfe.bin mtd0] it shows mtd options and do nothing.

Now am Stuck on this firmware cant downgrade/upgrade or restore to original linksys firmware.

Due to this reason i cannot get proper internet speed help needed.

Try after unlocking: mtd unlock /dev/mtd0 (never mind if it tells you it cannot unlock)
Code:
mtd -f write new-cfe.bin /dev/mtd0



Those commands have to be executed from the Command Line Interface (telnet/Putty) and not from the GUI

Moved this thread to the appropriate forum (see the forum guidelines)

Is there a reason to use a 2021 firmware?

New builds are http://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/ for 2022 and newest public beta http://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2022/05-23-2022-r48954/

followed by a nvram reset and reconfiguration from scratch.

As for wifi speed, read https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=327595 and note that no matter what speed the router shows under optimal settings, the connected clients limitations apply and also affect the speed the clients can achieve.

400 mb/s is not too shabby Smile

Be sure to turn on CTF&FA for best throughput and use best wireless settings see the link from the joker.

But even with optimal settings and circumstances real throughput is not more than 350-400 mb/s

(Whether you use stock, DDWRT or fresh tomato)

If you are flashing via CLI and not webUI (should be able to flash via webUI from 2021 build), then use:

https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2022/

Keep in mind, you will likely have to use either curl or wget http (not https) if you use CLI. For example:
Code:
cd /tmp
wget http://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2022/05-23-2022-r48954/linksys-ea6900/linksys-ea6900-webflash.bin
write linksys-ea6900-webflash.bin linux
reboot
