NV2 - long association time

RouterOS Wireless Networking

hi,

if wireless-protocol=any on CPE is used there is sometimes very big delay than all the clients associates. On APs with 50-60 clients it can take around 3+ minutes difference between the first associated client and the last one. And the first one doesn’t associate not so quick too.
I don’t know whether the CPE has to scan for all the permutation of channel and protocol sets or the AP answers on a qiery with currently used protocol. Hints?

Is there something which can speed up the process? Except the scan-list - the one we use is relatively broad one - and I would like to have it untouched (altohought I can probably use not the lower and upper value of the channel range but a distinct frequencies preventing the CPE sending probes on frequencies which are not modulo 20).

Thanks

If the wireless-protocol is set to any your CPE has to scan through every channel for all the protocols until it finds your AP.
Set it to NV2 and it will be a lot quicker.

probably but then I would lost a way how to quickly change the protocol back to 802.11 in case of a problem. And are you sure the CPE has to scan for all the protocols? It may be that the CPE scans for AP by sending a probe and AP responds ’ I am here and I am using this protocol’ or the protocol negotiation can be part of the association process. I didn’t tested the difference yet.
