Hello, 

Router model - VX420 - G2v

Hardware version/ firmware version is unknown 

I am experiencing issues with our home internet - we have only a handful of devices on our network which include mobile devices and laptops. When we utilise our laptop devices on network, speeds are great and no issues occur. When we use our mobile devices, internet is bad and we are left turning our wifi off and just using 4G. I will note that the mobile devices were able to use internet just fine on wifi for the first few months of having internet at home. It is like something has changed and now we are left with this issue. 

I highly doubt it is a device limiation issue with our router as there would be a total of 5 devices on network.

I was wondering if there were any other settings I could change on the router to prevent this from happening?

I have tried the following:

• wifi off and on
• forget network / re add 
• connected to wifi and remained within arms reach of router 
• restarted router 
• iphones have newest software updates 

Any help would be appreciated!
