OC200 + EAP245(EU) v3.0 : The wifi up/down speed varies (constant sinusoid)
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello everybody,
We are a french monastery and have 21 EAP245 plus 5 EAP225 outdoor. All of them have the latest firmware release. The network we created is essentially dedicated to ToIP, using VoIP phones (Yealink/Cisco) and Voip Softphone (GS Wave from GrandStream) installed on 4 android smartphones.
We encountered the following issue : frequent disconnection on our SIP session, and very significant variations in flow (down and up) as well as in latency which also varies cyclically from 8 to 1600 ms every 5 or 6 ping! You can see on the following screen copies some tests we made.
We tried a lot of suggests made on this forum (adjusting transmit power, reducing overlapping, etc.). So, we will gratefully welcome any suggestions to help us resolve this issue ... and pray to thank you for your help.
Hello,
Many thanks for your answer. Since our former message, we anticipated you advice and have updated OC200, EAP245 and EAP225 Outdoor to last EU firmaware :
No major changes were noticed : we saw the same period of very bad latency with a bit better value (around 1200 ms).
Following your advice we are going to test step by step on each band separately. Do we keep 20/40 MHz channel width for 2.4GHz and 20/40/80 MHz channel width for 5GHz for our tests ? or is it better to use 20MHz width only ?
Many thanks for your kind help !
