Mac address change after logic board swap = wifi connection issue
crwdns2934249:0crwdne2934249:0:
Hi,
I'm having problems with wifi connectivity. Recently i've swapped out the logic board which seemed to work fine, I reset SMC and NVRAM to bring it back to speed (it had slowed considerably after the swap, but a reset of the NVRAM fixed this issue) but now have run into a problem I don't know how to take any further: with the swap the serial number as well as the mac address have changed, but the problem is that in my home network I cannot connect to the wifi any longer. I do not have problems connecting to a new wifi network, but it seems the mac address change is causing issues with known networks. So far i've tried only my home network as a known network.
Now, I've deleted all login info for the network and rejoined it a few times now but no joy. I'm thinking there is a possible conflict with the old mac address. But why would there be? The router is not set filtering mac addresses, nor should the ISP be. I read about changing the mac address manually, i guess i could give this a try, but it would only make sense with the old number...wich i don't know where to find anymore.
Hm. Any thoughts welcome. Thanks

OK, so, replacement board is in, all working fine... except the WiFi connection at home. I'm a little bit stumped on how to proceed. Wifi DOES work at other location. What I've tried so far is:
'''On the Mac:'''
* Created new Location
* Deleted wifi home connection in the network settings and keychains
* Cleared out SystemConfiguration files / rebooted
* * updated to latest OS High Sierra (was not working in previous Sierra after board swap, still not working)
* Renewed leases on every step
+
'''On the router:'''
* Changed SSID & Password
* Set no password
* Changed DHCP number (because i can)
* Different devices connect fine to the same router (iphones & macbook)
* Can not change wifi channel its a 2,4 GHZ model only / its a provider branded router with minimal configuration options (o2 6341 - germany)
+
'''When trying to connect i get two types of messages:'''
* WiFi requires WPA2 password / invalid password (password IS correct / also changed it as a test)
* Something like move closer to router (I'm sitting right next to it)
+
So, all told, I don't know what else to try. My hunch is it has to do with the changed board (mac address) as it occured at the same time, which might be a coincidence, but then it might not. I guess the next thing I could try, do a complete new install without a restore and test it that way.
Any other suggestions would be most welcome.
Thanks!

Meanwhile, after a re-install of the os and some more fiddling (adding these proxy settings *.local, 169.254/16) and AGAIN editing 'locations' today i had some connectivity to the home router but it would drop continuously and re-assign itself. Pings would take a very long time and browsing the internet was not possible due to dropping connection.
Where can i go from here?
Not having much luck so far. What is odd i think is that my mac address only has numbers, no letters. Could that make the router reject the connection? Hmm. I've reset the router, no joy.
