Surge suppressors that work

Hi all,

This week we went to get two new APs online (a UBNT M5 and M2 rocket titanium)- this is our first Netonix WISP switch in use (a WS-12-DC on 1.3.9).
We're using Ubiquiti's surge suppressor with both APs.

At first the APs wouldn't auto-negotiate a rate with the switch at all, and cable diagnostics were coming back all funky (3 pairs good, 1 bad; 3 pairs bad, 1 good, really weird lengths, etc). When cabling directly from AP to switch, they'd negotiate at 1000mbps no problem and cable diagnostics came back good.

Was able to get them to auto-negotiate 100mbps rates WITH the UBNT surge suppressors after doing a firmware upgrade on both APs.
I've done some reading on the Netonix forums about issues when using surge suppressors, so my main question now is: Has anyone used UBNT's surge suppressors with a Netonix switch and seen 1000mbps rates? If so it points to an issue with our setup; if not, we need to either find new surge suppressors or do like what sirhc does: ditch them and do our grounding differently.

Can everyone post which surge suppresses HAVE worked flawlessly with their WISP switches?

Thanks!

Surge protectors are OK if you want to use them but grounding should be as I suggest regardless which is following engineering standards that cell carrier use.

Don't you ever wonder why they do not suffer losses like WISPs do? - GOOD GROUNDING SYSTEMS

I really hope you read both these grounding posts

Most important thing is to make sure tower ground bonded to electrical service ground or your EThernet cables will be the bond and you will go through equipment.

You should have a dedicated ground wire run from each radio/antenna that is shorter than your Ethernet cables between your radio to switch to earth ground. Your Ethernet cable run should be at least 10% longer (use liberal service loops if needed)

Read the following thread and do the wiggle test. Poor plug/jack mating is probably your issue.

Thanks for the replies guys, am definitely wanting to update grounds to follow sirhc's guidelines. The site I'm speaking of is remote and off grid, nontheless, the generator and tower are both grounded but their grounds are not bonded :willy:

Will do the wiggle test next time we're at the site and report back - would be amazed if we were able to get 1000mbps just from jiggling the cable a bit.
