Hello

My PC is (Ethernet) cabled but i also need it to be simultaneously on WIFI in order for my Iphone to sync automatically/wireless with Itunes.
(Itunes only syncs wireless if both PC and phone are on WIFI)

I've disabled "Priority & VLAN" on the ethernet network card, but my WIFI does not have such setting.

The problem: When I use my PC , at some point it will cut off ethernet, leaving only WIFI
However, via WIFI i do not have access to our work server....

Also, although ethernet is cut off, it still says under network connections that it's connected.

Any help would be appreciated.

EDIT: in fact I do still have access to the server, but it's my mail application that can no longer connect;

We have a mail system that runs on our server and i connect by starting and .EXE file on my pc
When Itunes starts syncing it interferes with this program causing it to malfunction

thanks,
I did this for the ethernet, but wifi does not have this setting
the second part "how to manually set network priority "doesn't apply to my case

There is a fundamental problem here. You cannot put the WiFi adapter and Ethernet in the same PC on the SAME network and expect them to work simultaneously. The problem is that if both adapters are on the same network, Windows has no way to determine which adapter to use so it's simply not a valid configuration. Yes, there are exceptions to this. For example, some Ethernet adapters allow for "NIC Teaming" or joining of multiple adapters together to act as one "team" but this is not the case for just any random set of adapters.

As for the original issue - I'm not buying the premise that the iPhone and PC both have to be on WiFi in order to perform a sync. Why should the iPhone care? So long as it is on an IP network that can reach the PC it wants to sync with, why should it care if the PC is connected via Ethernet or WiFi? The only reason that I could see for this would be if your router was purposely configured to segregate WiFi and Ethernet so that these are treated as two separate networks.

As an example, I'm guessing that your iPhone can probably connect to the Internet over your WiFi network. The instant your iPhone hits the router, everything beyond that is no longer WiFi. Why should it be any different for iTunes?

This sounds more like a configuration problem than anything else.

If it is for some reason absolutely necessary to have the WiFi and Ethernet adapter in the PC active at the same time, then the WiFi and Ethernet adapters should be configured as two separate and distinct networks.

I am not an expert at all, so am sure what you say is true

But as i saw quite a few posts mentioning that this is possible and that the router is able to "separate" the 2
(though clearly that's not happening in my case)

As for the itunes matter: it did work before via ethernet and wifi, but since we changed internet provider it no longer does.
So when i tried to find a solution, i saw several mentions that it only works via wifi and I thought maybe apple changed something recently...

We have only one box (router/access point) so why it would separate wifi & ethernet is beyond me

I changed the setting for my ethernet but could not find this setting on my wifi adapter but it's working, at least I see both connections when I 'hover' over the network icon in the system tray.

Update: I see now the wifi is not carrying any traffic

My PC keeps dropping the WiFi connection..., makes using Logitech Flow a p-i-t-a!!! 🤷‍♂️

Taking @hsehestedt 's advice, I connected via wifi to one router and ethernet to another. This made no difference until I bridged these connections. Now both are carrying traffic.

In fact , all works fine with both ethernet & wifi on; my iphone syncs with itunes & i have internet.
But it can not connect to the external server (and thus also no access to our communication system)

I tried to bridge both, but then i no longer have internet

And can not find any setting in the router that seperates wifi & ethernet

Guess i will have to dig up my Iphone Cable ....

Just to follow up : our new internet box is sitting before our firewall, so that's why the wifi was seperated .
Have now switched off the wifi on it and reconected our old wifi acces point to our switch (after the firewall)
