Hi. I'm no networking expert, just savvy enough to have installed a FW Gold to protect my home network and run a Ubiquity AP system from it.
There's a bunch of info online about why the new Ford cars are failing to connect to home wifi, and even in this thread the commenter mentions he runs a FW Gold and had to change to another router to get it working (not the fault of FW, fault of the Ford networking stack).
The key fix that seems to address folks issues are two-fold, and I'm hoping for your advice on how to apply them to my FW Gold setup (set up in Router mode).
Thanks in advance! Below I an including the 2 fixes I need to make to my network to get my dang car on the wifi to do OTA updates.
Fix #1 I can't figure out how to apply.
So I've tried all the things that you guys are trying... 2.4 to 5, signal strength issues, password...it turned out what fixed mine is the XXX.XXX.0.X. It had to be a zero. What led me done that path was I turned my phone's hotspot on with the same ssid and password and it connected to my phone with no problems. The only difference I could find was the IP addresses.
Fix #2 I can't figure out how to apply.
The solution is - in whatever is doing the DHCP on your network - be it your cable modem router / WiFi, your own WiFi router, or a more complex network setup (Omada, Ubiquity, Apple Airport devices, etc)... the KEY - the fix - the solution is this - you CAN NOT have a domain name for the LAN the SYNC vehicle is getting it's address from. If you have a "local search domain", "local domain", "search domain" (the name changes based on the DHCP software on your network gear) - the SYNC vehicle will ASK for a an IP, the server will give the IP with the local domain, and the SYNC device will sit there and stare at itself... and you get the nice "SYNC can not connect" error. REMOVE the local search domain (usually it's like "lan", "guest", "local") from the DHCP config on your router / DHCP server - and try to connect again from the vehicle and your SYNC device will connect and be super happy...
TLDR ; if you get the "SYNC can not connect" error when attempting to connect to your WiFi network, look at the DHCP setting on your WiFi router and REMOVE the local search domain and things will work.
