I have a few wireless links setup that the ping times look good for a few minutes then jump from 4 or 5 ms to 2150 2300 9 7 back to 2150 and then fine again for 2 or 3 minutes. It usually goes to a “Request timed out” for 3 to 6 times before it goes back to normal. Then repeats it all again. This customer is litterally right across the street. My signal Strength is -53 DB on the Client side and -63 on the Main AP Side. Anyone have any idea’s how to resolve this. I am not bridging anything on the network, everything is routed.
In my experience this can be caused by interference.
Trees in the path even if its close with excellent signal.
If the signal strength is too high (ie. overloading the receiver)
‘Noisy’ enviroment
The high ping times are probably retransmits.
Things to try:
A different channel
Check the ack timeout to see if its abnormal
If you have access to a spectrum analyzer check for a repeating spike in noise at the frequency and the various resonant frequencies.
Try a bandwidth-test in one direction using UDP. See if its occuring in one direction.
try to configure at Data Rates
don’t set to default
look at the wireless registration table on the tx/rx rate side
set you’r data rates which show by tx/rx rate at good ping times
if tx/rx rate show 36Mbps so set you’r data rate to 36Mbs too
i solve this problem
sorry.. my english language so bad
brofreekers,
I have try your suggestion, but when I set from default to a fix tx/rx(for example 24Mb) but the total bandwidth on the AP result 24Mb that in real it become 12Mb. Other suggestion?
The only solutions I have found it to upgrade all my gear to 5 ghz. I am about 1/2 way there now and my users on the 5 ghz have no problems. Only the 2.4s are still having problems. I guess it is interference of some sort.
LOL, I have the same problem in the 5.xGhz space. I have changed all the sectors to 24dbi panels that can work from 5.1 to 5.8 so that I have plenty of channels to move to.
I have 70 customers already equipped with fixed access point that work only at 2.4GHz .
for me is impossible to solve in this way.
I’m trying to change ficed rate but the issue is the same, if I set to 1 Mb all the access point goes at 1 mb.
What I need is a possibility to set the rate for a single client at wireless level.
One question,
and if the root caouse of the the eretik ping is the P2P connection?
I read somewhere in this forum that someone has problem with the number of connections opened and the eretik ping issue.
I chenge the channel and it works.
But after 3 days the same issue. Now I change again… but I cannot stay to change channels each time.
Perhaps Mikrotik team could answer comment somthing. I’ve had this problem from 4 months.
