If you've found that your download speed is great, but your upload speed is abysmal, I've got a possible solution for you lot. I struggled with this issue for a while and decided to write down my findings in a web log postal service in case I, or anyone else, runs into this in the futurity.

In fact, this is the second such blog mail service I'k writing: a couple years ago, I hit the the inverse event and documented the solution in a blog mail service called Got slow download just fast upload speeds over wireless? Here's a fix. That post has had several hundred thousand views and helped many people (check out the comments—I even got a spousal relationship proposal), then I'1000 hoping this post will exist useful too!

Here's your tldr: upgrade your router'southward 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 flake intermittent, but everything from google maps to gmail suddenly got very sluggish. I accept one of their higher tier Internet plans from Comcast, so this was pretty disappointing.

I ran a bandwidth exam on http://www.speedtest.cyberspace/ and the results were roughly the aforementioned beyond all of my devices:

Slow upload speed

At 57 Mb/due south, the download speed was great; however, the upload speed was a mere 0.17 Mb/south, which is pretty much unusable. In fact, I had to re-run the test several times, as occasionally, the upload portion of the test would go stuck and never complete.

The solution

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

Finally, I stumbled upon the solution: a firmware upgrade. My router, a Cisco/Linksys E1200, was using firmware version 2.0.02. I went over to Linksys' support page, found my router, and saw that a newer version, ii.0.06, was available. Here'due south a snippet from the release notes:

            Product:          Linksys E1200, Wireless-N Router Classification:   Firmware Release History ____________________________________________________________________   Firmware 2.0.06 (build six) - Pocket-sized cosmetic browser-based GUI update. - Various minor issues fixes.   Firmware two.0.05 (build ii) - Enhanced WAN-to-LAN performance when Net connection type is set to PPPoE.   Firmware 2.0.04 (build 1) - Resolved issue with decrease in download speed when WMM is enabled. - Resolved effect with decrease in upload speed when QoS is enabled. - Increase throughput performance when parental control is not enabled. - Resolved issue with incorrectly handle RTSP under certain circumstances. - Resolved PPPoE connection effect with a few ISPs.   Firmware two.0.03 (build 10) - Added dual-stack lite (DS-calorie-free) support. - Allow native IPv6 and 6rd support to be enabled simultaneously. - Implemented Wi-Fi Protected Setup lock-down mechanism to forestall brute force attack. - Resolved consequence with not being able to admission 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 peculiarly interesting, as they set up bugs with WMM (which was the cause of problems in my previous blog mail service), QoS, and more.

I figured information technology was worth a shot, downloaded the 2.0.06 firmware, and installed information technology through my router'southward admin UI. The instructions for upgrading the firmware will non exist the aforementioned for all routers, but here's roughly what you need to exercise:

  1. Go to [http://192.168.1.one](http://192.168.i.one/) and login to your router. If you've never washed this, look for instructions that came with your router or practice a google search to find the default username and countersign.
  2. Click on "assistants".
  3. Click on "firmware upgrade".
  4. You should encounter a page similar this:
    Upgrade firmware page
  5. Click "Choose File" and select the firmware file yous downloaded.
  6. Click "Commencement Upgrade". DO Non unplug your router or click anything else in the concurrently; let the upgrade complete!
  7. Wait a minute or then for your router to reboot.

The results

Afterward 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/southward, but now the upload speed is fast too, at 11 Mb/s, or virtually 70x faster than what information technology was earlier. Woohoo!

I promise you lot institute the mail service helpful. If your router has a different firmware upgrade process, leave a comment with the steps you followed so others can find information technology. Happy spider web browsing!
