Reply to comment by OorPancake in TIL that cheap, un-shielded USB drive enclosures drastically reduce Bluetooth range by SomeGuyNamedJay

I'll take your word for it. But on my home network, I run a 2.4ghz band and a 5 ghz band. In my farthest room from the router, I can connect to the 2.4ghz but typically not to the 5ghz. I thought I read somewhere to do 2.4ghz if you want to maximize range. Was that BS and it's just a fluke, or is there something to it?

I think 2.4 has less range but can penetrate walls easier. 5g has a longer range but can't penetrate walls as easy. It's strange.

Ok, maybe that is it because the signal has to go through multiple walls and to another floor of the house.

I could swear that I did read it somewhere to go 2.4ghz if you are having trouble connecting to 5ghz. I didn't make it up myself.

It's not.

2.4GHz suffers from less attenuation (it penetrates walls better) due to the longer wavelength, but the cost is a reduction in data rates. That's why it's seen as a legacy standard these days..it's low(frequency) and slow(data rate). But I'm not saying you should disable it on your home router though, it's fine as a fallback (maybe split your SSID's though).

In Enterprise deployments though, it's all about coverage with 5GHz
