Installed Snapshot and lost admin functionality

Installing and Using OpenWrt
1

Hi everybody,

I just purchased a TP-Link AC1750 Archer A7 V5 router and had successfully installed OpenWRT. I was getting very slow speeds though (>50mps on a 1 GB connection). I tried a ton of fixes (software offloading, firewall adjustments, etc.) but finally made my way to Reddit looking for a solution.

On an old Reddit forum they recommended installing a snapshot specific to my router. I got the snapshot from the below link:

https://mirror-03.infra.openwrt.org/snapshots/targets/ath79/generic/

But since installing the snapshot I can’t access the router admin page (the connection is refused according to multiple browsers). That said, the internet and wireless still work and I can ssh in to the router and run some basic commands on it. However, commands like “opkg” aren’t recognized when I try to use them to update the software to revert it back to its original state. I’ve also done a hard reset that didn’t fix the issue.

I’m ultimately trying to TFTP this router back to its original TP-link OS but it doesn’t seem to be taking. If anyone knows how to get it back to the TP-link OS or even back to where I can access Luci and basic OpenWRT commands again that’d be great.

Thanks in advance and sorry for the novel.

This hardware is not fast enough to handle routing at 1 GBit/s, it's native speed maxes out around ~170-200 MBit/s and software flow-offloading might push that up to 300-400 under ideal circumstances.

You want filogic 830, x86_64 or similar devices instead.

Well crap, I missed that page before the install. So I guess I did essentially just strip out the GUI. That makes sense why ssh works but using the IP doesn’t and the time limit explains the upgrade part (I just installed it a few hours ago).

Thanks for the response, I guess I’ll mess around with re-installing it piece by piece via ssh
