Okay so I've been on so much tech support for the past couple days and no one knows how to solve this, so I'm hoping someone here can point me in the right direction.

Specs:
FIOS Internet
Wired and Wireless network using a bridge for most of the wired connections
Tested a mix of PCs, Mac, Hackintoshs, Tablets both wireless and wired connections on my home network.

The Problem:
When trying to download files from specific servers file transfer rate is very (15 k/s) slow. Most of the time I uploading and downloading files in the range of 500 MB - 4 GB. So I'm thinking it's a server issue, but not after everything that I tried.

Testing:
My speed test results are:
Ping:16ms Download: 82.02 Upload: 37.76

Same slow speed on all computers and devices on my home network only on a hand full of sites (The ones I use most)

Tested servers on another network: Normal speed and transfers in the range of 1-2 MB/s. Tested on FIOS and Comcast networks.

Tested other servers/sites on my home network and get normal speed. Someone actually downloaded a 700MB file from one of the servers in question. Uploaded the same file to google drive, I then downloaded it and unziped the file. While this was happening I started downloading the same file from the same server at the same time. By the time I unzipped file from my friend my file was only 2% downloaded.

Pings to the servers are responding fine:
64 bytes from 192.254.236.251: icmp_seq=3 ttl=52 time=77.223 ms
64 bytes from 192.254.236.251: icmp_seq=4 ttl=52 time=76.318 ms

No Errors or Stops in the Trace Route to those servers


The only thing that seems to help is Releasing and Resetting the DHCP Lease, but this only seems to help for about 5 minutes.

So I'm at a loss of what to do from here. I'm out of ideas. Anyone? Please?

So you have your isp come in to their wireless router (isp-router). You have a 2nd router in bridge mode that connects to the isp-router wirelessly (bridge). To the bridge you have wired connections to various devices as well as wireless devices. Is that right?

Close, it's a wired connection from the Router to the Bridge.. See if this clears it up.
ISP --> Router
Router --> Bridge through a wired connection
Devices are connected to the router wirelessly, wired directly, as well as the bridge.
The Desktop computers are connected wired into the Bridge.

The [strike]error[/strike] problem is on every connection, wired-router, wired-bridge and wireless-router.

Tested on a 780MB file

So Downloading normally it's going at about 30k with random spikes up to 1MB, but stayed below 100k most of the time.
Downloading through the Unblock site didn't seem to want to want work, only wanted to download the first 6-10MB on all files tested.
Modified the host file with the recommended IP settings and now we are getting an average of 500k-1MB. I think that modifying the host file may have worked!? I'm going to keep downloading stuff throughout the day and will update later on.

This seemed to have worked! Thank you!

Just a quick follow up, any idea on how this happened?
