I have no trouble maxing out my network speed when I am connected to 5G wifi. But when I am connected to 2G I am maxing out in the low 30’s. This isn’t a device-related issue because I have the same issue with my phone and laptop.

This doesn’t have anything to do with my router either. I have Unifi access points around my house that are hardwired to the network. So my router has no idea what version of wifi I am using but the speeds are very low when I’m on 2G.

I also know that my AP’s are not the problem because the AP’s use an SSID that is different from my router’s SSID. When I connect directly to the router’s radio the same thing happens – when on 5G I max out my download speed but when I’m on 2G I’m stuck in the 30’s.

To summarize, when I connect to 5G on AP’s or the router I get max speed. When I connect to 2G on AP’s or router I get 30’s. Same result with different devices.

I do not have a lot of interference from other 2G networks so that is not the issue. I do have a lot of IOT devices and cameras on 2G but they are all connected to the AP’s SSID. When I connect directly to the router, there are maybe four or five devices connected to it and they are low bandwidth IOT devices, so there’s no congestion on that wireless network. I should be able to get maximum speed.

Any idea what the heck is going on?
