Running 19.07.0-rc2 r10775-db8345d8e4 on my R7800.
On this firmware - and all of the previous OpenWRT versions I installed since I purchased the R7800 during summer - I get an occasional loss of internet connectivity on some wifi clients. Perhaps 3-4 times a day. Wifi connection symbol in windows stays on, but loss of internet connectivity is detected by Windows. I also confirmed I cannot ping any other devices on the LAN. The loss of connectivity lasts about a minute or two - and then it is working again. If I disconnect/reconnect Wifi it is resolved (until it hits again)...
Wired Ethernet seems OK, so I do not believe this is a WAN issue - but rather some Wifi/routing issue.
Few weeks back I tried switching the wifi firmware to the "-ct" version:
[ 11.994391] ath10k_pci 0000:01:00.0: qca9984/qca9994 hw1.0 target 0x01000000 chip_id 0x00000000 sub 168c:cafe
[ 11.994431] ath10k_pci 0000:01:00.0: kconfig debug 0 debugfs 1 tracing 0 dfs 1 testmode 0
[ 12.005519] ath10k_pci 0000:01:00.0: firmware ver 10.4b-ct-9984-fW-012-6acc9b999 api 5 features mfp,peer-flow-ctrl,txstatus-noack,wmi-10.x-CT,ratemask-CT,regdump-CT,txrate-CT,flush-all-CT,pingpong-CT,ch-regs-CT,nop-CT,set-special-CT,tx-rc-CT,cust-stats-CT,txrate2-CT,beacon-cb-CT,wmi-block-ack-CT,wmi-bcn-rc-CT crc32 2f261949
...but this had no effect on this problem (on the other hand I now witnessed a crash of this firmware in the kernel log; but only one).
Does anyone have a clue here? Seems there are a lot of happy R7800 users here, so I am puzzled why this hardware is acting up for me...
I did try a few. The original one in 19.07. Then switched to a -ct version i pulled . And now I see another one in the hnyman build. All give problems. I could try a fourth - but not sure which one to pick and by which argument. Just looking for a stable connection.
Perhaps someone here with a rock solid performing 7800 could share which version they are using?
Any other ideas? Considering if I should purchase some other hardware; wife and kids are complaining
EDIT 0: apologies for the botch link... should be fixed now.
EDIT 1: ugh, i just can't get seem to get my links right today
Regarding audio/video, there is a recent thread by an experienced R7800 user having issues that turned out to be related to router location (a dead spot). In that thread there are some suggestions about tracking down wifi interference from neighbors...
FWIW I use the ath10k-ct driver and ath10k-ct-htt firmware on the r7500v2 (an older and slightly different cousin of the r7800) running a recent build from "master". The device is an AP only and will run for 30+ days without reset.
I see the log entries that you reported earlier but can't attribute them to wifi drops that are the fault of the wifi firmware. That said, I do have wifi drops (somes multiple times per day) on both iphones and android phones. I suspect there are multple causes not least of which is these devices going into deep sleep states. For my use case, these drops are tolerable enough that I don't log packets in an effort to see if this can be improved at the router.
Based on the feedback going in different directions here, I am unsure what is the right choice. I now used 19.07.1 r10911-c155900f66 for the last month - no improvement. Few days back I did a "Reset to defaults" and manually configured it up again to rule out some stale configuration change messing up things. No improvement.
Is it worth attempting to downgrade to 18.06 as suggested by some? Security updates are important to me (in fact the reason I use 3rd party firmware).
I am now seriously considering buying another device to get a stable setup. I really do not care about traffic shaping or insane bandwidths. But availability and responsiveness is everything. My old ASUS N56-U chugging along with Padavan firmware would run solid for 6-12 months and NEVER exhibited this flakyness; and that is dated hardware to say the least.
Would the Archer C7 be a sensible alternative to R7800? It is wonderfully cheap
