If you've establish that your download speed is bang-up, only your upload speed is bottomless, I've got a possible solution for you. I struggled with this result 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 future.

In fact, this is the second such blog mail service I'm writing: a couple years ago, I hit the the inverse issue and documented the solution in a blog mail chosen Got tiresome download but fast upload speeds over wireless? Here'due south a set up. That post has had several hundred 1000 views and helped many people (cheque out the comments—I fifty-fifty got a marriage proposal), and so I'thousand hoping this post will be useful too!

Hither'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; information technology was a bit intermittent, only everything from google maps to gmail 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.cyberspace/ and the results were roughly the aforementioned across all of my devices:

Slow upload speed

At 57 Mb/s, the download speed was great; notwithstanding, the upload speed was a mere 0.17 Mb/southward, which is pretty much unusable. In fact, I had to re-run the exam several times, equally 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 goose egg helped. I also checked with Comcast to ensure in that location were no issues our outages in my expanse, 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 ii.0.02. I went over to Linksys' support 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 Classification:   Firmware Release History ____________________________________________________________________   Firmware 2.0.06 (build six) - Modest cosmetic browser-based GUI update. - Various small issues fixes.   Firmware ii.0.05 (build ii) - Enhanced WAN-to-LAN operation when Net connection blazon is set to PPPoE.   Firmware ii.0.04 (build 1) - Resolved issue with decrease in download speed when WMM is enabled. - Resolved outcome with decrease in upload speed when QoS is enabled. - Increment throughput performance when parental command is not enabled. - Resolved issue with incorrectly handle RTSP under certain circumstances. - Resolved PPPoE connectedness result with a few ISPs.   Firmware 2.0.03 (build ten) - Added dual-stack low-cal (DS-lite) support. - Allow native IPv6 and 6rd back up to be enabled simultaneously. - Implemented Wi-Fi Protected Setup lock-down mechanism to prevent brute strength 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 especially interesting, as they fix bugs with WMM (which was the crusade of bug in my previous blog mail service), QoS, and more.

I figured it was worth a shot, downloaded the ii.0.06 firmware, and installed it through my router's admin UI. The instructions for upgrading the firmware will not exist the aforementioned for all routers, but here'southward roughly what you need to do:

  1. Get to [http://192.168.1.1](http://192.168.one.i/) and login to your router. If you've never done this, look for instructions that came with your router or exercise a google search to find the default username and password.
  2. Click on "assistants".
  3. Click on "firmware upgrade".
  4. You should see a page like this:
    Upgrade firmware page
  5. Click "Cull File" and select the firmware file you downloaded.
  6. Click "Commencement Upgrade". Do NOT unplug your router or click anything else in the meantime; permit the upgrade complete!
  7. Look a minute or so for your router to reboot.

The results

Subsequently 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/s, but now the upload speed is fast too, at eleven Mb/southward, or nigh 70x faster than what it was before. Woohoo!

I promise you found the post helpful. If your router has a different firmware upgrade process, leave a annotate with the steps yous followed so others can find information technology. Happy web browsing!
