Hi,
We installed a Netbox 5 link that is 25.5 Miles and we are not getting anywhere close to the signal level’s we have gotten with other older equipment, or what any of the wireless link calculator’s estimate (Mikrotik link calc gives a -45, UBNT with RocketM5’s in place of RB911G’s says -57). We can’t seem to get anything better than -78.
I’m starting to wonder if there is maybe something with the unit. I’ve already sent support output files to Mikrotik support but was wondering if anyone sees something possibly wrong with the config.
I’ve tried several versions of RouterOS (6.18 – 6.23) and none seem to make a difference. Also noticing since going to 6.18 or above the Current Tx Power tab on the wireless interface either shows 0dBm on 6.18 or no data at all on 6.23 but Mikrotik says that info is not applicable to AC). Also since going to 6.22 or 6.23 WDS seems to no longer function the same. I can see it dynamically use the bridge to create the wds interface, but the remote router where the Ethernet cable plugs into no longer pings or passes traffic. I guess to get around that I’ll take the route of going station-bridge. First things first though, we have been unable to achieve anything better than a -78.
I’ve tried using almost every channel from 5180-5765, and 20Mhz channels, AC/N Only, Nstreme,NV2,802.11 only, etc (possibly everything there was to try, although I don’t rule out that I might not have thought of something) Nothing seem to have any effect on the signal strength, and since we were replacing a 5Ghz link, the frequency we’ve ruled out as being the issue. We have used both Canopy 100 BH20’s, and UBNT Rocket M5’s for this link in the past with signal’s in the high 50’s/low 60’s. Plus any spectrum analysis at either location comes up clean.
These are both using UBNT rocket dishes (RD-5G34 34dbi on the AP side, and RD-5G30 30dbi on the Station side) and they are in known working condition.
The below is just an /interface wireless export verbose minus the security profiles for each end of the link.
Here’s the AP Side:
