I had another tread but it seems dried out, so tried again with new subject and experiances.
Some Apple devices, (not all, some work inmediately) can connect to a wifi AP and some other router on a remote ‘bridged’ router (some interface are bridged) plays the role of dhcp-server.
Now I have two networks, one allows most Apple devices to get an IP, but yet again not all. Where the other denies most Apople devices (but again, not all) an IP address.
Some Apple devices that are denied IP addres from the one network/dhcp-server have no issue obtaining similar from similar but other network. Apart from the IP address range and the physical nature settings are all exactly the same!
In both cases the devices login the wireless AP without problems (NO encryption, only mac filter in the access list) but the IP requested for (either dynamic or dynamic-assigned or fixed) is not handed out.
The status for that devics goes from “bound” for about 10 secs to ‘busy’ for some time (anywhere between 4 sec to some minutes) to go to ‘offered’ again. It takes ample seconds to hand it out and “bound” pops up again and the cycle starts again.
In the apple device’s network status doesn’t change at all..
We tried every possible setting in the dhcp-server field.
We tried the client as random dynamic client,
We tried the client with an fixed lease client and tried serveral setting here.
All to no avail.
Very frustrating…
We have couples coming in with two brandnew Ipads. One connects, no problem. The other just can’t get an IP???
Androids, window device or whatsover never have this issue. Only the ‘top’ brand Apple?
well, that kept us busy for half an hour. My employees IpadTouch 5th generation doesn’t have a “Console”.
There must be another way but in google we could only find a long explanatory manual on how to set it up. Since she already was late we decided to give it another try tomorrow. (I have no other apple devices at hand now…)
But how can it be that on one AP with dhcp server there is not a single problem where on another it has.
The only difference on the AP with the issue is that the dhcp-server is some hops (wireless and wired) away and together with some 8 other AP’s all interconnected with a vlan. The dhcp-server of this ‘Hotspot’ (It is not a real hotspot, just dhcp-server with mac auth. list) sits on a bridge interface that bridges several vlan’s for this purpose in this router.
The AP that works is just bridged to a bonded link that is bridged to another router that has also 2 normal ethernet interfaces in a new bridge to create one big office network. That all works fine…
Hi We will try to replicate your setup and problem.
We have tested wireless with different apple devices iPhone 4s, iPhone 6, iPad air 2, etc.
And they didn’t showed any problems with connection.
try to enable wireless debug and also dhcp debug on router.
Well, iOs or Apple. We see the issue with Apple iPads, Apple iPhones and Apple Ipod-touch. I seem to remember once we had someone with an Apple Macbook having the same issue.. So, Apple or iOS, whatever, they don’t work.
Haven’t had time today. Too many other issues to solve…
I am having the exact same issue at one of our clients. They have a CCR-1009-8G-1S acting as a router, a cisco sg300 switch, with a CAP-2n access point hooked up to the switch which is hooked up to the router.
The devices seem to stay connected to the wireless (I watched the registration table on the CAP and they don’t disconnect according to the uptime), but they keep requesting DHCP leases and the old IP they requested just shows up as “busy”. I set the devices to static on the mikrotik, so at least now they’re not burning through IP
We tried all suggestions post on this forum but to no help.
We have a 3 AP 2,4Ghz sort of ‘hotspot’ system. We authenticate mac addresses in the access list of each AP (depending which one will ‘see’ the client(s)) and all 3 hotspot APs are bridged with a vlan network that has one dhcp-server assigning addresses with dns and default gateway.
What is so weird is that some families walk in our office for access, both having a Ipad; one connects without problems and has internet access, the other connects, gets IP address but cannot get to the internet. Or sometimes does connect (registered in the registration table) but is not even getting IP address. IP is offered by dhcp-server but after some times goes to ‘busy’ or disappears to be offered again, and again, and again, etc. etc.
We also have some that say they can connect in one AP but on the other they get no internet access? Very weird.
I didn’t spend too much time on it because it needs extensive investigation and I just don’t have time for it.
Androids or normal laptop hardly seen the same issue. But Apple devices quit regularly, 90% I would say…
I tried now with interface queue ethernet-default just in case, but it did not help.
I think this is a general problem with Samsung Smart TVs, not really Mikrotik’s fault, but if you were able to solve it, it would be good for marketing.
Now I am wary of buying another router that only has gigabit ports.
I put the Airport Extreme in bridge mode as DHCP client, and the Airport Extreme, the TV, and the wireless devices connected with the Mikrotik DHCP server without problems.
