Hello, I have Leap 42.2. After some update relatively recently (or possibly after a change of VDSL provider and therefore of access point/router) wifi became unstable. It is an old-ish 2.4 GHz card that uses the rt2800pci driver. It is working, but after some time, pings to the access point/router become very slow (up to 3 seconds!) and packet loss appears. Network connectivity is noticeably flaky (slow loads, extrtemely laggy games, etc). The output of the dmesg command contains the following kind of messages periodically: [ 8488.700135] cfg80211: World regulatory domain updated: [ 8488.700139] cfg80211: DFS Master region: unset [ 8488.700140] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 8488.700141] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) [ 8488.700142] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz, 92000 KHz AUTO), (N/A, 2000 mBm), (N/A) [ 8488.700143] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (N/A, 2000 mBm), (N/A) [ 8488.700144] cfg80211: (5170000 KHz - 5250000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (N/A) [ 8488.700145] cfg80211: (5250000 KHz - 5330000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (0 s) [ 8488.700146] cfg80211: (5490000 KHz - 5730000 KHz @ 160000 KHz), (N/A, 2000 mBm), (0 s) [ 8488.700147] cfg80211: (5735000 KHz - 5835000 KHz @ 80000 KHz), (N/A, 2000 mBm), (N/A) [ 8488.700147] cfg80211: (57240000 KHz - 63720000 KHz @ 2160000 KHz), (N/A, 0 mBm), (N/A) [ 8489.835461] wlan0: authenticate with 70:50:af:cc:3b:02 [ 8489.851029] wlan0: send auth to 70:50:af:cc:3b:02 (try 1/3) [ 8489.853331] wlan0: authenticated [ 8489.854916] wlan0: associate with 70:50:af:cc:3b:02 (try 1/3) [ 8489.858363] wlan0: RX AssocResp from 70:50:af:cc:3b:02 (capab=0x1411 status=0 aid=2) [ 8489.858433] wlan0: associated [ 8490.006569] SFW2-INext-DROP-DEFLT IN=wlan0 OUT= MAC=00:0e:2e:e5:df:23:70:50:af:cc:3b:01:08:00 SRC=192.168.1.254 DST=192.168.1.10 LEN=308 TOS=0x00 PREC=0x0 0 TTL=64 ID=0 PROTO=UDP SPT=67 DPT=68 LEN=288 What can I do to fix or diagnose this? -- Yours, Mikhail Ramendik Unless explicitly stated, all opinions in my mail are my own and do not reflect the views of any organization -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Thanks! Could you advise how to fix this? I checked in YaST and "DHCPv4 server" is allowed for External Zone, while wlan0 is configured for External Zone. On 31 October 2017 at 08:55, Freek de Kruijf wrote:

Hi, but you'll want to allow "DHCPv4 client", not the server. Cheers MH Am 31.10.2017 um 15:19 schrieb Mikhail Ramendik:

Thanks, but it's not listed in YaST. What kind of rules would be needed? On 31 October 2017 at 15:26, Mathias Homann wrote:

Check with "iptables-save" in a terminal. Despite it's name It doesn't save the tables just list them. -- /bengan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I would use wireshark aka ethereal to find out if it is the router which takes its time to respond. Then you could try resetting the router. - -- Cheers Carlos E. R.

I would second checking the router. Our network regularly dies of an evening (when load is at its highest), and it always seems to be DNS on the router messes up.

The problem is that another computer, running Fedora, accesses the Internet just fine at the same time. On the other hand, a reboot did not fix the issue. I suspect it is a driver issue, but the only way to check would be to roll back the kernel to a version 1-2 months old and see if the problem disappears. Would this be possible? Or else it is some disagreement between the services in opensuse and the router...

Yes, just download previous kernel from http://download.opensuse.org/update/leap/42.2/oss/x86_64/

Highly unlikely, user space is not involved in actual data transmission once interface is up (i.e. client associated with AP and obtained IP address). -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
