i have a mikrotik 433 with XR2 Card connected to a sector 180 Deg
i have around 11 registered users & one of them is connected to 5 GHz but he owns around 30 users.
during the day ( working hours ) whenever i try to ping Google the ping goes up to 1500 ,1780 ms and times out…
also when i ping the Mikrotik AP from a very good signal ping goes up to 350 and 500 ms knowing that in the middle of the night or morning the connection is pretty normal,
i tried to change the frequency really worked hard on fixing it , but nothing …
1.can the problem be from outside the network ?
maybe the incoming internet connection to the AP Mikrotik is becoming slow or something ?
is it normal to have such high ping to the AP directly if the internet was slow ?
What is the ACK time on the Wireless registrations of the tower. If you only have under 20 connections on it it should be a dead give away as to who or what the culprit is. All ACKs should be under 50 More than. If not then it is likely that it is a channel confliction.
Make sure that all Clients are at ROS 4.16 or better if you are using MTs for the CPEs.
Do check for PTHROUGHPUT as well all connections should be high. The higher the better. If it fluctuates then the CPE could be the culprit if they are hammering heavy streams.
XR2s are 2.4GHz so they can be easily hit with excessive packets. You should move to a 5GHZ network with SR-5s.
2.4GHZ can only as an aggregate use 5.5Mb so it may be getting saturated. you should always use 5GHZ to feed 2.4GHZ users not the other way around. I was never happy when we did 2.4GHZ to 2.4GHZ users. You just get odd problems with latency and packets.
Post a screen shot of your registration tables with the ACK, PTHROUGHPUT, SNR, and the CCQ this would help. Thanks
Hmm looks good. Your overall connection is at 88% which means some of your conencted customers are fluctuating in and out of a good connection range. I know that this is probably said a lot to everyone on the forum but I am going to say it too. Please make sure that your AP and your clients are all running at the latest ROS I really like 4.17. I see that your AP is running at 4.10. Also I noticed that your country was not selected. Please make sure that the CPE and the AP are on the correct country code. Some ROS versions seemed to not work so well if they were different or not selected. ROS 4.17 is really rock solid with great radio connections. I saw an improvement from 4.10 when I went to 416. So do apply the update on the AP and CPE/relay(s).
Please also repost the wireless tables with the registration list. Please show the column the additional columns of:
Ack. Time out
Router OS Version
tx/RX CCQ%
P Throughput
Signal to noise
This will significantly help me see the culprit bad signal.
ok will have them posted soon,
but i have technical quick question,
can pinging my AP be high when the incoming connection is slow? , if i was Bridged with wds?
The best way to do a relay is the have the ap use AP bridged mode and use WDS. HAve the relay point use WDS staion with a wds dymanic. When you do bridge mode I have notice that the connection is not at the best download speeds. If you do AP with WDS to Station WDS and use NSTREME you can have the best speeds on such a setup.
To answer you question yes. If you have a slow connection on the bridge you can get a high ping time. I have seen this when the CPU is very high. Check your CPU it should not be getting pegged if so I would remove any packages that you are not using like hotspot DHCP ppp etc (ONLY if you are not using them.)
i think you have capped the data rates to 6 mbps hence ur pthruput is 4800 or less and the tx/rx is 5.5 mbps. therefore if the total bandwidth exceeds 5.5 which wld be happening during day time u must be experiencing increase in latency. take the data rate out let it be default. u r using tplink cpe’s??
yes ill do that, thank you
and yes i think i have TP-Link with all users
does that make any since ?
is there a preferred configuration or setting on TP link access points?
On TPLINK CPE enable AP Isolation and Set fragmentation and threshold to 512. Enable RTS CTS on ur AP side with fragmentation and threshold set to 512 on the AP as well. U will find these in the advanced and ur routeros shld be above 4.10. Preferrably 4.17. I have worked on this and have got optimul CCQ.

Guys I have been working on the network
And when I disconnected the isp link everything worked perfect
Ping was 3ms and 10ms max!
That means with no Internet the ping is normal
It is normal buddy because when u d/c the ISP link the clients ain’t receiving ne traffic. Just the ping packets which u r transmitting from the testing end. But when u put up the ISP link each radio is generating traffic individually and the AP has to handle multiple requests simultaneously.
Please post the registration tables with the requested ACK timeout, with the PTHROUGHHPUT and the CCQ. This will help narrow it all down a lot of problems. Thanks

do you have any qos? 11 clients in 802.11b cant work good, unless they had 256kbit/512kbit tarif..
what wlan throughput (mbit/packets) is when bad pings appear?
also when i ping the Mikrotik AP from a very good signal ping goes up to 350 and 500 ms knowing that in the middle of the night or morning the connection is pretty normal,
i tried to change the frequency really worked hard on fixing it , but nothing …
it looks like you have interferences from other network or 2.4GHz video transmiter
btw. at registration table most of your ap clients are tp-link. did you try change ap mode to 802.11-only-G and at clients to G? If you had not interferenced from other networks you can boost you network at some clicks…
ok here is some more details might help troubleshooting,
i’v been working on the problem the whole weekend,
what is i did is the following:
configured a new station facing the Main AP with:
Edimax access point connected to a sector
5.8 link with xr2,grid,mikrotik rb133
i connected 3 clients on it,
the ping is pretty much normal and the internet is very good
i think its all about wireless interference but changing frequency is not helping,
note: there is another AP mikrotik in back of my AP.
ping is sometimes going high even if im the only one registered on the AP
i got really tired
can’t we have a real and professional solution?
