Hello Everyone,
I use a Linksys E1200 v2 and i recently upgraded my firmware to: Firmware: DD-WRT v3.0-r40559 mega (08/06/19)

now i cannot connect to my VPN server. i was told it's either because my router is not supported (it is) or the firmware is not supported (not sure about his).

customer service will not help with firmware issues because they are afraid that it could brick. Can anyone offer a solution or an alternative firmware version that is reliable and stable

thanks,
Mike

1. read this to start with..
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324087

2. when you need help, start with details...more details, better chance to get help...

3. very likely, your router to have a very bad performance with VPN, if VPN module is present at all...
with single core CPU @300 Mgz VPN will be like 1-2Mbit max..

Thanks for getting back to me,
i'll give the detailed version. I've used Astrill VPN on my Linksys E1200 v2 router for the last 7 or 8 years. I had the same firmware from 2013 for many of those years, but about two months ago, it would not connect and I upgraded, based on the recommendation of a tech support agent. It was unstable, but generally worked until last night. Now I've tried to upgrade again. When installing the applet, it will fetch the files and take me to my server page, but the status cycles from waiting for network to authenticating to get_config and then to disconnected. The log and response from my vpn company are below


Hi Albert,

ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19)

This error indicates, either your router is not supported with the Astrill VPN applet or the firmware version is not supported which is flashed on your router.

Best regards,

I also appreciate the link you said, but i've been advised that I must a mega or big build and that minis will not work

I hope this is detailed enough for me to get some help because i've been trying to fix it myself for the last 24 hours and i'm just not tech savvy enough.

As you are new I will transfer your post to the right forum (Advanced Networking but Broadcom would also do)

To get the best out of DDWRT and the forum, read and follow the forum guidelines:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324087

Please carefully read and follow the forum guidelines.

We know the router you have Linksys E1200v2 but we cannot give decent support if we do not know what exact build you are running, K2.6 or K3X, mini , mega etc.

dd-wrt.v24-40559_NEWD-2_K3.x_mega-nv64k.bin

this is my firmware build. I will find this in the broadcom forum and post there as well

thank you,
MIke

Search my posts for the MIPS upgrade path for Broadcom and then upgrade to the current release. 40559 is junk. Or, just tempt fate and flash directly to the current release: https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2020/11-03-2020-r44715/broadcom_K3X/

Try adding the following to the startup script and reboot.
