We use PMP450i to connect small offices to our Municipal Network.
Generally all of our applications work well and we treat wireless as an alternative to fiber, for sites that don’t need a lot of bandwidth.
But our Digital Display Units (DDUs) don’t work. These are Android based units that just need to connect to a web site and download data. The DDUs work when sites are connected over fiber rather than fixed wireless. And a laptop that uses the same fixed wireless connection is able to connect to the web site. Everywhere that we try it (two locations in the field and a mockup / test site) we have the same problem. There’s just something about the combination of DDUs and PMP450i that doesn’t work well together. Has anyone seen anything similar? Any suggestions on things we should check?
Thanks

Do you use DHCP, and if so, are the DDUs receiving the correct network configuration? Are there any network diagnostic tools on the DDUs themselves?
Thanks for your reply Simon. We have resolved this issue. Our Network team specified “no MTU check” on the MPLS service where it was being carried over the wireless links. We suspect something was happening with MTU fragmentation but, admittedly, the problem and the reason that our solution worked aren’t really that well understood. One other piece of info is that the service was working before when it connected to an http site but not when it connected to the https site.
