![]() I even had a consultant and TAC to evaluate this. I’ve spend quite some time analyzing this problem, but haven’t found any reason for this problem. Our tests are done with a setup with a PC, Macbook, 2 x iPad Air 2 with latest iOS and an iPhone, within 2-5m from the AP where the problem has been reported. We also tested at 13, but with no difference. We also lowered the TCP MSS from default to 1250. ![]() I can’t conclude much on that, since we also have single-band clients (2,4GHz) on other locations that also has problems – even where we can’t find any significant interference. ![]() Even though the test wasn’t perfect, on one location it seemed that the problem only was present on 5GHz. We even tried to disable either band, one at the time, to force clients to a specific band. On the small locations that we surveyed, we have about 9 AP’s, including outdoor AP’s and only about 10-15 clients - total - so I don't think it's a load issue. On some locations we found some interference from PIR-sensors – but only on channel 1. We have surveyed some locations for interference with a NETSCOUT AirCheck. I have been advised to make a proper site survey, and that has been done – to some extend. sometimes a reboot seems to solve the problem – for a while, which could be related to DCA, but I’m not sure. I can't tell if it's the reboot or other location/evironment that makes the difference. In several cases I’ve tried to bring the failing AP’s to my office, but I can’t make the fail again. Replacing the AP’s helps and the users seems not tho have any problems afterwords. It seems that’s it’s always the same AP’s that the users complain about. ![]() Primarily I get complaints from users of iPads, but also others, like PCs, MacBooks, Surface – primarily clients being connected to 5GHz. This happens on both schools with many clients and on locations with ten or less clients. However, the last few month I’ve been receiving several complaints from users on different locations, telling that their clients randomly disconnects or are unable to connect. Since I had not received any other complaints or error-messages from other and very different users, I concluded that it must have been a client-side-issue. $$įor some time I have experienced that a specific type of IoT-device, has had a hard time, staying connected to our WiFi. Yes, I know many of above models should have been replaced - and I want to - but. I work for a medium size muncipality and I provide wireless network for many different types of clients, on schools (high density), offices (medium to high density) and Day Care (very low density) ![]()
