Wireless Devices stay connected but internet stops working

dfoolio

Hello,

I have a Sophos XG home setup with the Sophos AP 55C configured for wireless. I have a strange issue where the devices at home which are wireless, will be working fine, but then the internet just stops working, but the wireless stays connected.

For example: my iMac which is setup wirelessly will be working fine when I am working on a VPN connection to another site, but then the RDP will become completely unresponsive. I check the wireless and it shows connected. When I try to launch a web page, It sits forever and then says cannot access site. However, everything SEEMS to be working okay. The only way for me to fix this, is to turn off the wireless, then back on and it resumes working perfectly.

This occurs with our phones as well as any wireless connected devices after awhile. It tends to last about a week per device, sometimes devices (like my iMac), require the wireless to cycle once every few days. This is especially the case if I have not used the device for a couple days.

I am not sure where to start looking, I figured this could be the AP, but another device, such as my phone will work fine when the iMac goes out. I am thinking this could be a network issue or possible DHCP? I am not.

Wired devices seem to work just fine.

Thanks.

    Hi Dfoolio,

    Could you please check below steps when this issue occurs: 

    1. Are you able to ping IP address of the AP?

    2. Are you able to ping gateway IP address? 

    3. Are you able to ping 8.8.8.8? 

    4. Have you notice this issue across all the devices in your home network?

    5. Does it recovers without any changes within 5 to 10 minuets? 

    6. Is there any other wireless access point in your home network? 

    Thanks,

    Hi Patel, Please see my additional updates below

    1. Are you able to ping IP address of the AP?

    The AP is Pingable from devices that still have network, the AP is not pinging when the device falls off the network

    2. Are you able to ping gateway IP address?

    I did the ping test when my iMac fell off, and I had 89.8% packet loss pinging the gateway, all other devices are fine when they are connected

    3. Are you able to ping 8.8.8.8?

    No it doesn’t ping from the device with internet issues

    4. Have you notice this issue across all the devices in your home network?

    Yes but it’s not at the same time. It’s intermittent, sometimes it’s a phone and sometimes it’s a laptop, phone, appletv or a desktop.

    5. Does it recovers without any changes within 5 to 10 minuets?

    It doesn’t recover

    6. Is there any other wireless access point in your home network?

    No, we have the one AP

    Hi dfoolio,

    Can you check what is the AP firmware version? If it is not updated please update it by navigating to Backup & Firmware > Pattern updates > If there is new pattern update available click on install. 

    Thanks,

    Hi Patel, I have the latest version installed.

    Hi,

    please provide a simple network diagram showing how your AP is connected eg is it using PoE via an injector or via PoE capable switch?

    Hello,

    The WAP is connected via power injector to port 3 of the firewall.

    I have a managed switch connected to port 1 of the firewall. Port 2 is the WAN.

    Here's a screenshot of the interfaces:

    Hi,

    I haven't given up. I am thinking about your wifi setup and your use of wifi networks rather than wifi of a LAN.

    What happens when you force th iPhone onto a 2.4ghz channel

    Haven't had a chance to try again per the request, but in the past, it's the same results.

    Additionally, I did the WiFi to LAN because of an earlier problem:

    We have a Lutron Casseta smart lighting system which is plugged into the LAN. So whenever we used wireless siri devices to control the lighting (everything on the wifi), it would only work 25% of the time and couldn't communicate with Apple's protocol. I even tried configuring a Raspberri Pi to be a repeater but it just started causing the devices to replicate host names.
