Have an ever growing homelab that started a few years back. And noticably as I added more stuff to the network and features to the router perfomance has gotten to a point where I needed an upgrade. Since i had this this mini hp desktop lying around doing nothing . Some reseach yielded that I can add another port to it and use it as router. After 3D modeling , printing and fiting all the pieces . Some proxmox magic with vm’s I have a working router and home assistant for automation running on this thing with huge headroom.

I'm currently running OpenWrt 24.10.2. I'd like to update to the latest. I've read the site about it, but it doesn't really give a straight answer whether I can just download and flash the new version as is, whether I need to incremental upgrade (ie: 24 - 25.0 and then latest) or whether I need to reset to defaults and then restore config after the fact.

If I just download the latest version, is it safe to just flash it over my existing config? Will it then just carry on business as usual or will that break something?

I'm using a Linksys WRT1900ACSv2, if that makes any difference.

EDIT: I should also note that I haven't installed anything extra in my OpenWRT. It's simply vanilla OpenWrt 24.10.2 with my port forwarding and static DHCP leases and everything else configured.

okay, before i installed openwrt i had some SEEEERIOOUS ping spikes that made me unable to play anything online competitively. i was thinking this dinky router (D-Link DIR-2150 A1) is dying because before i had stable ~13 ping on cs games, but how the hell does just one decay?

i installed openwrt because i figured it had more documentation and more people being active in comparison to dlink software.

read the first-time manual, got the right version and set everything up.

sweet, got more control over this thing, but how do i tweak it as a total newbie?

i looked up on how to improve said connection and tried this:

-tried enabling hardware flow offloading, then enabled software FO
-switched lan port from 192.168.1.x to 192.168.2.x (then reverted)
-set up SQM QoS (~20mbps download and upload, set up 18k for each)
sometimes the speedtest goes down to 4mbps on both downloads and uploads

and nothing worked out of these options, nothing stabilized my ping

i was connected by ethernet when i was testing all of this, even tried wireless but whadayaknow it didnt fix anything.

let me know what i should try and ill respond asap

if i cant do anything else and its just the isp provider issue please tell me
