I have a single PC that is recently experiencing horribly slow download speeds on the Internet.  Upload is fine.  All other PC's on this network are unaffected and downloading fast.
Our broadband speed is 10/10.
Ran through Malware Bytes, etc = No Change.  Flushed DNS & Removed Temp Internet Files = No Change.
Checked a host of other things from Layer 1 on up.

Any Ideas?

Have you tried http://speedtest.net/ to see what speed you might be getting? It will give you a semi accurate indication of your actual speeds depending on where you set it to test against.

How does the client connect to the internet, wireless or wired? If it is wireless are there any new SSIDs recently that might be on the same channel? Have you updated the wireless drivers?

Do you have some funky internet package, focusing on upload? Most Internet connections are faster for download then upload, mine are 9.3Mbps upload and 0.97,bps download.

Has anything changed on the network adapter settings, e.g. MTU size?
Have you tried another port on the switch?
Is data transfer between this PC and others on the network slow or only the Internet?
You state you have looked from layer 1 up, have you done a packet capture to see if packets are getting mangled, dropped?

Ok so it turns out that this PC's NIC was set to 100mbps FULL.  I switch it to Auto and BAM everything began to work fine.

Thanks.
