If you've found that your download speed is great, only your upload speed is abysmal, I've got a possible solution for you lot. I struggled with this result for a while and decided to write down my findings in a weblog post in case I, or anyone else, runs into this in the future.

In fact, this is the 2nd such blog mail I'thousand writing: a couple years ago, I hit the the inverse issue and documented the solution in a web log mail chosen Got tiresome download but fast upload speeds over wireless? Here'south a set up. That mail service has had several hundred g views and helped many people (bank check out the comments—I even got a marriage proposal), and then I'm hoping this post will be useful too!

Here's your tldr: upgrade your router's firmware.

Symptoms

I noticed that on all my devices - a Macbook Pro, iPhone, Windows desktop - webpages were sometimes taking a long time to load; it was a bit intermittent, but everything from google maps to gmail all of a sudden got very sluggish. I have one of their higher tier Internet plans from Comcast, so this was pretty disappointing.

I ran a bandwidth test on http://www.speedtest.internet/ and the results were roughly the same across all of my devices:

Slow upload speed

At 57 Mb/s, the download speed was swell; notwithstanding, the upload speed was a mere 0.17 Mb/s, which is pretty much unusable. In fact, I had to re-run the test several times, every bit occasionally, the upload portion of the test would get stuck and never complete.

The solution

I tried rebooting the router, the cablevision modem, tweaking a agglomeration of settings, merely nothing helped. I also checked with Comcast to ensure there were no issues our outages in my area, and of class, everything was fine.

Finally, I stumbled upon the solution: a firmware upgrade. My router, a Cisco/Linksys E1200, was using firmware version two.0.02. I went over to Linksys' back up page, found my router, and saw that a newer version, 2.0.06, was available. Here'south a snippet from the release notes:

            Product:          Linksys E1200, Wireless-N Router Nomenclature:   Firmware Release History ____________________________________________________________________   Firmware 2.0.06 (build 6) - Minor cosmetic browser-based GUI update. - Various modest bug fixes.   Firmware two.0.05 (build ii) - Enhanced WAN-to-LAN operation when Net connection type is set to PPPoE.   Firmware 2.0.04 (build 1) - Resolved event with subtract in download speed when WMM is enabled. - Resolved issue with decrease in upload speed when QoS is enabled. - Increase throughput functioning when parental control is not enabled. - Resolved result with incorrectly handle RTSP under certain circumstances. - Resolved PPPoE connexion upshot with a few ISPs.   Firmware 2.0.03 (build ten) - Added dual-stack low-cal (DS-light) support. - Permit native IPv6 and 6rd support to be enabled simultaneously. - Implemented Wi-Fi Protected Setup lock-downwards mechanism to prevent animate being force assail. - Resolved issue with not being able to access the browser-based GUI via HTTPS when newer versions of Internet Explorer or Firefox is used. - Added Danish back up in the browser-based GUI.

The notes for version 2.0.04 are specially interesting, equally they fix bugs with WMM (which was the cause of problems in my previous blog mail service), QoS, and more.

I figured it was worth a shot, downloaded the 2.0.06 firmware, and installed it through my router'southward admin UI. The instructions for upgrading the firmware volition not be the same for all routers, but here's roughly what yous need to practice:

  1. Go to [http://192.168.1.i](http://192.168.i.1/) and login to your router. If you've never washed this, look for instructions that came with your router or do a google search to find the default username and countersign.
  2. Click on "administration".
  3. Click on "firmware upgrade".
  4. Yous should see a page like this:
    Upgrade firmware page
  5. Click "Choose File" and select the firmware file you downloaded.
  6. Click "Start Upgrade". DO NOT unplug your router or click anything else in the concurrently; let the upgrade complete!
  7. Wait a minute or so for your router to reboot.

The results

After the router restarted, I re-ran my speed test, and the results were much nicer:

Fast upload speed

The download speed is still a zippy 57 Mb/south, but at present the upload speed is fast also, at 11 Mb/south, or nearly 70x faster than what information technology was before. Woohoo!

I hope you found the post helpful. If your router has a different firmware upgrade procedure, go out a comment with the steps you followed so others can find it. Happy web browsing!
