I am using a TP-Link Archer C2600 router. Before I installed the latest snapshot-build yesterday, I used an older snapshot-build from february 2019. In LUCI, the following informations was displayed:
Together with the Snapshot-Build from february, the package "ath10k-firmware-qca99x0-ct" was installed and everything worked fine. Unfortunately, I did not remember the exact package version.
With the newest Snapshot-Build from yesterday installed, I'm facing massive problems with data rate and ping as soon as I am a little further away (about 5 meters) from the router. It makes no difference if I keep my personal settings or reset everything to default while upgrading. I noticed that the package "ath10k-firmware-qca99x0-ct" in version "2019-06-28-7651f5bb-1" is installed here and I found out, that the problems are only there with package "ath10k-firmware-qca99x0-ct". Not with "ath10k-firmware-qca99x0". But I need the advanced features. A little bit frustrating.
Now I think that there are two possible solutions and I'm asking for your advice. Either trying to find a older snapshot-build (maybe exactly the old one from february 2019) or installing only a different/older version of the "ath10k-firmware-qca99x0-ct" package in hope that this will solve the problems.
sorry for my late answer and thanks for the idea to building from source. The last days I tried to build old versions. But something I think I'm doing wrong. Maybe your or someone other knows what.
First I successfully build the newst snapshot version with: git clone https://github.com/openwrt/openwrt.git ./scripts/feeds update -a ./scripts/feeds install -a make menuconfig make -j 7
For building a older version in searched the git log and found some older commits. With "git reset --hard 9c0c1c44013003616e2f5c55c062430dbda3cce5" i thought it will work. But after checking "menuconfig" and another building-process i figured out, that the kernel and git version in Luci was older, but all packages (including the athk10 ones) was still up-to-date!
Can you guide me which commands I'll need to build an older OpenWRT-Image (for example from commit 9c0c1c44013003616e2f5c55c062430dbda3cce5)?
Without knowing I'm thinking that my issue was: ./scripts/feeds update -a ./scripts/feeds install -a
If I'm not doing these two commands "make" is creating some error massages which are meaning that some dependencies are missing. Also it can happen that the building-process will fail.
Your example 9c0c1c440 seems to be from 18 July 2019, so you should investigate and find the correct feeds-specific commits from that date for each feed (that you use packages from).
(But you may need to use "feeds/scripts install" to adjust the package data after resetting all fedds correctly).
thank you for your hint with the other git repos. Next to openwrt, i also cloned luci, packages, telephony and routing, "reset --hard" to a commit near to the commit from openwrt-repo. After that, I created a folder with the name "feeds" in the root-location of "openwrt" and copied the other main folders of the git repos into it.
Before I was able to build I also done the following:
./scripts/feeds update -i (to create missing index-files) ./scripts/feeds install -a (to install all packages) make menuconfig (to select what i want and what not) make -j 7 (start the building process)
All worked as expected but unfortunatly I doesn't found my old, 100% working combination for my TP-Link C2600 router.
I was headless to upgrade a snapshot build without making a copy of all things.
How can it be that before the upgrade to a newer Snapshot build a throughput of about 200 Mbit/s (stable) was possible and with newer builds only a maximum of 90 Mbit/s (unstable, ping dropouts) on 5 GHz? On all tests I had the same distance/location to the router.
If I reduced the distance to the router before the upgrade, even over 400 Mbit/s were possible. With newer builds it stays exactly at 90 Mbit/s but it will be more stable. There are no dropouts if I'm right next to the router. But a few meters further on it starts and the throughput is extremely irregular (1 Mbit/s, 20 Mbit/s, 0 Mbit/s, 90 Mbit/s).
