Wireless signal strength decreases with distance from the source. They are literally doing the best they can with what they’re getting. With low speeds streaming services like Netflix and Hulu produce terrible pictures. The faster your internet connection, the faster your devices receive information, and the better the quality of the final output. Data transmission is shown in Mbps (mega-bits per second). Internet speed is a measure of how fast it can transfer data. Getting the right internet speed is crucial as it ensures you can do the things you want without problems. When I ask… common answers include “they said it was the best”, “you are making me nauseous” and “can you just make Netflix work”. What confuses me most is the fact that it worked fine for ~5 days.Few people know what internet speed they’re paying for. My laptop has a Broadcom BCM4313 wireless chip, which means whatever driver it is running on is not the proprietary driver provided by Broadcom (I have it downloaded but even with the suggested patches it won't build). Since the change to slower speeds occurred at reboot directly after installing the cisco software, I uninstalled it, rebooted several times, and ran similar tests, but it was still slow. Also, the above speed test was run with nethogs running in another terminal to verify that something else wasn't eating my bandwidth. If I plug the laptop into the router using a spare ethernet cord, I get full speed. Even loading the webpage controls for the router I am connected to is very slow. I can get about 20-30 kB/s download, even when I clone a git repository from the other SL7.1 computer on the same local network. Hosted by Time Warner Cable (-) : 216.958 ms 
When I run the exact same speedtest on my laptop I get: Retrieving configuration. I get similar speeds from my android phone connected to the same router through the wireless using the app. Hosted by BrescoBroadBand (-) : 59.823 ms Here are what I have measured so far:įrom a different computer also running SL7.1, wired into the network the speed test gives: Retrieving configuration. I downloaded a python wrapper for 's tests and have been trying to do some diagnostics, but can't seem to interpret what is going on.
The next day I started it up and seemed to have slow connection speeds. Then, I installed a new piece of software (Cisco Anyconnect VPN Client) tested that it worked, then shut down the computer.
The wireless worked out of the box, and worked at full speed for nearly a week up until about 36 hours ago. About a week ago I installed a fresh scientific linux 7.1 image onto my laptop.
