Re: [WISPA] Mikrotik Problem - 900Mhz-WDS-incremental speed degradetpZero then drop- repeat.
PAul, I'll try updating the firmware, that makes sense to try. Upgrading from 3.10 to 3.28, is it likely that I can do that remotely without my client configuration getting lost in the process? (I know how to upgrade packages, I just didn't know if config files are consistent through all the V3.X revs) Tom, We replaced both XR900s on both sides of link. So its not a bad radio card. We did not replace the RB 411, yet. Its also the first time we used a 411 w/ 900Mhz card, so we dont have a track record for knowing compatibilty, yet.

I have a problem with Mikrotik I have not been able to solve. Wondering if anyone has any insight. A summary config is I have a 433AH setup as AP with 1 XR900 and 1 R5H (5.8Ghz). The Cat5 Ethernet port goes to a SMC VLAN switch, where the SMC tags and untags VLAN ID, and continues to the Backhaul Radio. My point here is the MT itself does not have any VLAN configured. I need everything to act as a True Bridge, so I'm using WDS on everything. Both mPCI cards are set up as AP and then WDS interfaces configured. The R5H sector has one subscriber, so there is one WDS interface created for that. The XR900 has two subscriber points. So there are two WDS interfaces set up for the XR900 sector, one for each subscriber. So all three WDS interaces and the Ethernet (to backhaul) are all bridged togeather under one Bridge. SubscriberA has a 433AH also, and actually is a repeater site. So it has two mPCI each configured for WDS, and then the WDS ports bridged togeather. The primary mPCI that connects to the above first AP, is set for WDS Slave. This subscriberA (repeater radio) works normally. I can run MT bandwdith test continually at consistent speed. As well, the subscriber for the R5H sector above also is set up for WDS Salve, and works properly, and tests consistently with Bandwdith test. SubscriberB for 900Mhz sector is the problem. It is a RB411 w/ a 24V-1A PS, w/ XR900. Originally it was set for WDS Slave also. It is now set for WDS Station, and performs the same as if WDS Slave. When running MT Bandwdith test both UDP or TCP, Sitting at the 433AH AP's winbox, I get the following results TXing it works perfectly and consistently. But if doing a receive test It starts out at about 800 kbps, then slowly reduces speed incrementally, down to 500 kbps, to 300kbps, to 100kbps, etc, down to Zero. When it reaches Zero mbps, the radio link disconnects, and immediately restarts itself. Speed starts back up at 800 kbps or so, and the same thing repeats. If doing Bi-directional tests of course the same thing applies, because it receives also. Noise is low at teh SU, about -67, and -74 at AP. At first I thought it was noise at the IP, because occastionally SNR gets very low. .But SubscriberA has a lower signal at -84 and does not experience the same problem. Just for grins, I tried playing around with TRansmit power at the SubscriberB, but that had no positive effect. As well, as a test, I disabled the second WDS interface to SubscriberA, and no change. To be clear... SubscriberA and SubscriberB each have their own WDS interface configured on WLAN1 of the 433AH AP. I am using embedded MTOS V 3.10 on each. What is causing this problem? Why is speed received from my SubscriberB incrementally degrading and breaking link? Bridge loops? Is my config valid? RB411 Bug?

Tom, Be sure to upgrade the bios firmware as well when you go to 3.28 You can upgrade the firmware with no loss of config, but to upgrade the bios you have to be in the CLI. System routerboard print (shows you the version you are running with upgrade available) Then type system routerboard upgrade and then reboot We have been experiencing a few odd issues as well.

...with no loss of config is not exactly true - it depends on what version you're running before. Some upgrades brick, some do it flawless. If you're coming form anything in 3.x to 3.28 you should be ok, though I'd upgrade to 3.13 first.
