**Q: What kind of upload speeds are owners getting with this device? I recently purchased it and I get 250mbs download but a mere 5mbs upload.  help.**
A: Upload speed is determined by your internet service provider (ISP).  It will not be specific to the device itself.  I have hard-line internet to all my computers in my home.  The hard lines can support 1000mbps in either direction, but my ISP gives me 200mbps download and about 12mbps upload.  Typically when an ISP advertises your internet speed, they target the advertisement of the download speed, with a much slower upload speed.  If your AC1900 device can download 250mbps, it can definitely upload at that speed, but your ISP caps your upload at 5mbps.  You could maybe call your ISP and ask if there are options for faster upload.

You can test the device itself by doing a file transfer to and from another device on your same WiFi network.  For instance if you have two computers and they’re both connected to WiFi, you do a file transfer from the 1st to the 2nd, then again from the 2nd to the 1st.  The speeds should all be identical and depending on the size of the file transferred, you’ll see the maximum transfer speed of the device itself.

For example, my hard line connection supports 1000mbps in both directions.  When I run a speed test of my internet service I get 200 down and 12 up, but when I do a file transfer from one hard line device to another hard line device in my home network, I get roughly 1000mbps in either direction.  

Think of the device speed like a highway that has a 1000mph limit, but when you access the web, you’re given two cars provided by your ISP.  The first car takes internet traffic to your devices from the web (download) and the second car takes information from your devices to the web (upload).  The first car is a sports car and while it can’t max out the speed limit, it’s still pretty fast.  The second car, however, is a jalopy, and barely moves at all.  The payment you give your ISP determines what two cars they give you.  Some ISPs can give you the same car for both.  That is, your download and upload speeds are the same.  This is not the standard most the time, however.

TL;DR - Call your ISP and upgrade your service if you want better upload speeds. It’s not the device that’s causing the slowness.

**Q: Can i use this to create a windows mobile hotspot (transmitter) from my wired pc to nearby mobile devices?**
