Re: HotSpot Design

Use a signal detection tool with your smartphone to see if you get signal everywhere. Better yet, use the client registration list to see your smartphone's signal strength from the radios. The access points can typically provide a stronger signal as they typically have higher power transmitters and...

Re: I have a stupid IDEA

You mean to daisy chain multiple units from the same power supply? Usually where POE out is provided you can power a second one, but not indefinitely. You are going to hit the power limits of not only the power supply (which you are trying to augment with a 5 or 10A version) but also the injector, t...

Re: Vlan tagging in Point to Point with SXT Lite 5

Re: Addresses per Mac In Hotspot

it depends on how your access points are connected and configured. It would be best to test with either 1 or 2 and try to connect simultaneously 5 clients behind a single access point other than the hotspot controller and see if it works. If it doesn't, increase the number to the amount you want. If...

Re: RB751U-2HnD joke in a box

Is your other access point still running when you are testing the RB751U-2HnD? (as in are they both sitting next to each other?) For the frequency I generally find it best to avoid 2412 and 2462 as although the router seems to support it well, not every client device does when I test it. It's too ba...

Is the QRT G going to be just plastic like the SXT/SEXTANT/OmniTik/912G Outdoor or is it going to have some sort of RF Shielding? That has been the main obstacle preventing me from pursuing the Routerboard's integrated radios.

That helps a lot, I thought you were talking about two different access points. So there is just a single device, with a single bridge. Is the DHCP server assigned to that bridge as well? You may need to make sure that your DHCP server does not have "Add ARP for Leases" checked, even if the server i...

I believe you want only one device running the hotspot (including dhcp, etc) and the second device acting only as a bridge and the two connected either via cable, wds, or something similar.
