We recently installed Qustodio (a parental control software) on our child's iphone. It requires 500 and 4500 UDP ports on the router's firewall to be opened to be used by Qustodio's VPN. After Qustodio installation, it works sometimes but every now and then the VPN connection would drop together with the wifi connection to the HG633 router. When that happens, the only way to get Wifi connection to the phone back is by disabling the VPN, which we then lost the ability to use the software. This issue only happens at home when the phone is on wifi.
I've searched this community posting for a solution but couldn't find any.
So please can you check and advise on how this issue can be solved? Maybe we need an updated firmware/router or some specific way to allow those ports for VPN to be opened on the router?
Have you tried separating the 2 wifi broadcast channels, then try just keeping the iphone connected to either the 5Ghz or 2Ghz channel to see if this stabilises or if one of the channels is more stable than the other.
Log into the router and manually change the SSID (Wi Fi) name of the 5ghz channel.
I often find it is better to keep the 2 broadcast channels separate. For example, I have changed mine, and call one Home2Ghz and the other Home5Ghz.
Some devices can drop the connection when the SSID's remain the same.
Also, you can try manually setting the wifi channel for each broadcast channel. Try channel 6 for the 2ghz channel and 44 for the 5ghz channel.
Give this a try and see if the wif connection improves.
