My iPad dislikes the AX3000 Wi-Fi.
For long time I have used an AX3000 along with a TD-W8968 as modem.
All my devices worked OK but recently the ADSL speed dropped, so I asked another provider to install FTTH. They installed a Huawei GPON HG8145V5. I deactivated wi-fi in the Huawei and used the wi-fi in the AX3000. All devices worked just fine: Desktop and TV using Ethernet, two iPhones, laptops and an appliance on wi-fi. But the iPad Pro refuses to connect to Internet.
Unsuccessfully I did everything I know to make the iPad access Internet. I even restored the iPad to start from scratch without success.
Then I activated the wi-fi in the old ADSL router and voila the iPad connected to Internet. Furthermore I reactivated wi-fi in the Huawei and the iPad got access to Internet as well.
In short: The iPad refuses to access Internet through the AX3000 wi-fi, but access Internet in the Huawei or the TD-W8968.
The question is: why the iPad dislikes the AX3000 wi-fi while all other devices work just fine?
The weird symptom in the iPad is in the wi-fi settings:
"IP Address" 169.254.64.175
"Subnet Mask" 255.255.0.0
"Router" (is blank)
"DNS" (is blank).
If I manually configure the IP in the iPad to 192.168.0.xxx the iPad connects to the router but still there is no Internet.
Resetting router and GPON didn't fix it.
Any idea on what's going on?
