Networking help request for a Non-Apple guy

outofluckchuck 604 271 May 19, 2016 at 12:30 AM
My landlord shares his internet connection with me and I helped troubleshoot his networking issues once. I know basic home networking and this is what I advised:
  • 2015 Before:
  • Ubee Cable Modem Gateway w/ DHCP Server connected to=>Airport Extreme 2nd Generation MB053LL/A with it's own separate DHCP Server
  • The Airport Extreme was connected to 4 Other Airport Express to wirelessly "extend" (repeat) the network, 3 of them were model MB321LL/A and one of them MC414LL/A.
  • 2015 After:
  • Ubee Cable Modem Gateway w/ DHCP Server => Airport Express MC414LL/Aas an extender.
  • When we did that, we found old iOS devices with old firmware that may have been causing network issues as well. We upgraded all Mac computers, iPads, and iPhones and it seemed to have worked better.

In addition to that, the a DirecTV Wireless Genie that, when set to either static or dynamic, will still choose any random IP and cause IP conflicts, so we just decided to take it off wifi and forgo On-Demand.

That solution was working well, and then they started receiving more issues. So they "fixed it" themselves.
  • Here is the current setup:
  • Netgear C6300BD Cable Modem Gateway (w/ AC wifi, but unused) w/ DHCP Server connected to=>Airport Extreme 2nd Generation MB053LL/A but this time as a bridge (using a different SSID than the Netgear), using the Netgear's DHCP.
  • The Airport Extreme is again connected to 4 Other Airport Express to wirelessly "extend" (repeat) the network, 3 of them were model MB321LL/A and one of them MC414LL/A.
  • I am connected directly to the Netgear Wifi Gateway, set my devices to a Static IP, but I still sometimes receive several DNS issues even when specifying any DNS: local ISP, Google DNS, OpenDNS.

On the Airport logs, you can see this happening on all the MAC addresses of the extenders:
  • May 18 18:54:57 5 Disassociated with station XXXXX
  • May 18 18:55:02 5 Rotated CCMP group key.
  • May 18 18:55:02 5 Deauthenticating with station XXXX (reserved 2).

I told my landlord:
  • the AC gateway ALONE will be better than running any of the older Apple Airports together
  • Using multiple extenders can cause issues
  • Using multiple extenders can reduce wifi bandwidth. 50Mbps on Netgear, 11Mbps on the extended network.
  • That it's not good to mix wifi draft-n, n, b/g extenders/routers.
‚Äč
As I mentioned before, my networking knowledge is limited to BASIC home networking.
  • Am I understanding this correctly?
  • Am I correct that we should just be using the gateway if it can reach every corner of the single family home?
  • Are there any other notorious Apple devices that may cause these wifi issues?
  • What else can I say to convince him to believe me?
I sometimes work from home and it has become nearly impossible to do that with such an unstable home network. TIA

I don't think your issue is apple related at all. I would simplify your network to trouble shoot the problem. I agree you don't need the extenders if the main Access point provides a strong signal to all corners of the home. Typically I am not a fan of all in one devices but in this case it might make the trouble shooting easier. So I would unplug all the repeaters. Then take all the devices off the access point. Bring them up one at a time and see what happens.

Have you checked for Chanel congestion?

If you have one router that is dual radio set to do N/G/B the router and you have an N device, a G, device and B device the router will run in B (For the most compatibly) and hopefully N on the other radio. But you might need to set this to be static vs automatic.

You also don't mention how many users or the size of the building is it just a duplex or multiple units, I would get a powerline adapter for the direct TV box, and use that for any extenders that you needed to avoid clogging up the wifi. As stated also check your channels, and what you are using for encryption.

Although channels are automatic, it seems the Apple wifi network has successfully switched to a separate channel. Separate from other neighboring channels.

About 2500 sq ft, single unit, 2 storey, 20 devices. I have considered a powerline adapter, but on demand is not that important to us.

Can the DNS issues be because of the extenders?

I would set up a 2nd router upstairs and one downstairs using powerline to link the 2 routers use opposite channels as there really are only 3 on the 2.4 band 1-7-14
