Why is my Synology RT2600ac mesh not allowing Wi-Fi calling on my iPhone to work correctly?

Your problem might be related to Quality of Service (QoS) settings on the Synology RT2600ac. By prioritizing your iPhone’s traffic, you can ensure smoother Wi-Fi calling. Here’s what I did:
1. Go to the Synology Router interface.
2. Navigate to the Traffic Control section.
3. Set up a new QoS rule for your iPhone’s IP address.
4. Prioritize this device as ‘High’.

This change drastically improved the performance and reliability of Wi-Fi calling for me.

I’ve encountered this problem before, and it was down to interference from other devices on my network. Here’s how I managed it:

1. Identify the devices on your network that might be causing interference, such as old routers, cordless phones, or microwaves.
2. Try keeping your router away from these interference sources.
3. Also, make sure your router is placed in a central location for better coverage.

By reducing interference and optimizing router placement, I saw a significant improvement in Wi-Fi calling reliability on my iPhone.

I had the same issue, and it was incredibly frustrating. It turned out that the router needed a firmware update. Here’s how I fixed it:
1. Log in to the Synology Router Management (SRM) interface.
2. Navigate to the Control Panel.
3. Click on System, then click on Update & Restore.
4. Make sure you download and install the latest firmware.

After updating, I found that my iPhone’s Wi-Fi calling feature was working seamlessly. It’s a quick fix that could solve your problem.

First, make sure that your iPhone’s iOS is up to date. Sometimes, an update can resolve connectivity issues. Next, check the Wi-Fi calling settings on your iPhone:

1. Go to Settings.
2. Tap Cellular.
3. Tap Wi-Fi Calling and make sure it’s turned on.

Also, try setting up port forwarding on your Synology RT2600ac for port 4500. This can help with the Wi-Fi calling feature by ensuring the necessary network paths are clear.

1. Access the router interface.
2. Navigate to the port forwarding section.
3. Forward port 4500 to your iPhone.

Lastly, confirm that your iPhone isn’t on a VPN, as this can interfere with Wi-Fi calling.

I encountered a similar problem with my setup. The culprit turned out to be the Smart Connect feature on the Synology RT2600ac mesh network. Smart Connect switches your devices between the 2.4 GHz and 5 GHz bands, sometimes causing a disruption for Wi-Fi calling. To resolve this:
1. Log into your Synology router.
2. Go to Wireless and then Smart Connect.
3. Disable Smart Connect.

Make sure to save changes and restart your router. Once I did this, my iPhone had a much more stable connection for Wi-Fi calling.

You might want to try resetting your network settings on your iPhone. Sometimes, the settings can get misconfigured. Here’s how:

1. Go to Settings on your iPhone.
2. Tap General.
3. Scroll down and tap Reset.
4. Choose Reset Network Settings.

Remember that this will erase your saved Wi-Fi passwords, so you’ll need to re-enter them. After resetting, reconnect to your Synology RT2600ac network, and check if Wi-Fi calling works. This method worked for me when I faced a similar issue.
