Wi-Fi in my partment in Thailand is very slow?

My Wi-Fi in my apartment in Thailand is really slow. My thai friends, who have Thai iPhones and whatnot have no poblem conncting to the Wi-Fi and is really fast as a matter of fact. But when I try to connect with my American Laptop and iPhone, it either won't connect or is just really slow.

The router is a ZTE router, and the model number is ZXHN F620
Maybe there's some sort of setting I have to change on my laptop to adjust it to Asian Wi-Fi standards?

if anyone could help me i would very much so appreciate it: )

Something wrong with my Credit Report?

Hi, so here s my situation. Yesterday I went to Sprint to buy an iPhone on a lease, as the guy put my info in the computer he said that my information would not appear, like my credit score was just not showing up. He even called like the main sprint people and they to could not find anything. I'm obviously the real me. I gave them all the correct information. I was wondering if anyone knows why something like this would happen. I also had applied to credit karma earlier that day (it's a website that tells you your credit score) . So I was thinking maybe the information can't be pulled by two different sources in the same day? If you feel like you know please help me out.
