If you've found that your download speed is great, but your upload speed is bottomless, I've got a possible solution for you. I struggled with this issue for a while and decided to write down my findings in a blog post in case I, or anyone else, runs into this in the hereafter.

In fact, this is the second such blog post I'm writing: a couple years agone, I striking the the inverse result and documented the solution in a blog post called Got slow download but fast upload speeds over wireless? Here's a gear up. That postal service has had several hundred grand views and helped many people (check out the comments—I even got a marriage proposal), so I'm hoping this post volition be useful besides!

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 suddenly got very sluggish. I take ane of their higher tier Net plans from Comcast, so this was pretty disappointing.

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

Slow upload speed

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

The solution

I tried rebooting the router, the cable modem, tweaking a bunch of settings, but zero helped. I also checked with Comcast to ensure in that location were no issues our outages in my expanse, and of grade, 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 folio, found my router, and saw that a newer version, 2.0.06, was available. Here's a snippet from the release notes:

            Production:          Linksys E1200, Wireless-Northward Router Nomenclature:   Firmware Release History ____________________________________________________________________   Firmware 2.0.06 (build half-dozen) - Minor cosmetic browser-based GUI update. - Various minor bug fixes.   Firmware 2.0.05 (build 2) - Enhanced WAN-to-LAN performance when Internet connection type is set to PPPoE.   Firmware two.0.04 (build 1) - Resolved issue with decrease in download speed when WMM is enabled. - Resolved issue 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 connexion issue with a few ISPs.   Firmware 2.0.03 (build x) - Added dual-stack low-cal (DS-low-cal) support. - Allow native IPv6 and 6rd support to be enabled simultaneously. - Implemented Wi-Fi Protected Setup lock-down mechanism to prevent brute force attack. - 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 support in the browser-based GUI.

The notes for version 2.0.04 are specially interesting, as they prepare bugs with WMM (which was the cause of problems in my previous web log post), QoS, and more than.

I figured it was worth a shot, downloaded the ii.0.06 firmware, and installed information technology through my router's admin UI. The instructions for upgrading the firmware will non be the same for all routers, but here's roughly what you need to do:

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

The results

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

Fast upload speed

The download speed is all the same a zippy 57 Mb/south, but now the upload speed is fast besides, at eleven Mb/s, or nearly 70x faster than what it was before. Woohoo!

I hope you lot found the mail service helpful. If your router has a dissimilar firmware upgrade process, leave a comment with the steps y'all followed so others can find it. Happy web browsing!
