Hello,
I have a few questions about R52 and R52N cards that are specific to 2.4GHz/G band.
Before in one site we had two PC’s with ~10 PCI cards, which worked in 2.4 and 5 GHz bands. These cards were connected to grid and sector antennas, and at that point wireless links were all working fine, except for the one motherboard that started failing. Since the the mobo’s were about 10 years old, we decided to replace all the equipment with 3 RB533GL and RB433AH boards, and a set of R52 and R52N cards.
Now I will do a fast forward to current situation:…we did replace old mobos with the RB equipment and now we face huge issues with antennas that work
in 2.4GHz band. It seems that all all antennas that work in 2GHz band have very poor rx-ccq (>10%) but very good rx-ccq (70-100%).
We tries to replace these links with Groove and Metal but still we can’t get a stable rx-ccq with clients.
All links that work in 5GHz band work fine.
Is there some known issue with R52, R52N or Groove wireless chipsets or something that would cause that kind of issue in 2.4 GHz band.
We actually decided to get new mobos and create a PC filled with old PCI cards, that should replace new RB equipment. But it still does not
make any sense that such an old equipment can be used to create more stable links than the current gen equipment from the official Mikrotik hardware.
