If y'all've establish that your download speed is swell, but your upload speed is bottomless, I've got a possible solution for you. I struggled with this consequence for a while and decided to write down my findings in a blog postal service in case I, or anyone else, runs into this in the futurity.

In fact, this is the 2d such blog post I'grand writing: a couple years ago, I hitting the the inverse issue and documented the solution in a weblog mail service called Got dull download only fast upload speeds over wireless? Here's a prepare. That mail has had several hundred thousand views and helped many people (check out the comments—I fifty-fifty got a marriage proposal), so I'm hoping this mail service will be useful also!

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 fourth dimension to load; it was a fleck intermittent, simply everything from google maps to gmail of a sudden got very sluggish. I accept 1 of their higher tier Net plans from Comcast, then this was pretty disappointing.

I ran a bandwidth exam on http://world wide web.speedtest.net/ and the results were roughly the same across all of my devices:

Slow upload speed

At 57 Mb/s, the download speed was great; however, 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, 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 nada 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, 2.0.06, was bachelor. Here'south a snippet from the release notes:

            Product:          Linksys E1200, Wireless-N Router Classification:   Firmware Release History ____________________________________________________________________   Firmware two.0.06 (build 6) - Small-scale corrective browser-based GUI update. - Various minor bug fixes.   Firmware 2.0.05 (build two) - Enhanced WAN-to-LAN performance when Internet connexion blazon is ready to PPPoE.   Firmware ii.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 functioning when parental control is not enabled. - Resolved issue with incorrectly handle RTSP under certain circumstances. - Resolved PPPoE connectedness issue with a few ISPs.   Firmware two.0.03 (build 10) - Added dual-stack lite (DS-lite) support. - Permit native IPv6 and 6rd support to be enabled simultaneously. - Implemented Wi-Fi Protected Setup lock-downward mechanism to forestall brute force assault. - Resolved issue with non existence 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 two.0.04 are peculiarly interesting, as they ready bugs with WMM (which was the crusade of problems in my previous blog post), QoS, and more.

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

  1. Go to [http://192.168.1.ane](http://192.168.1.1/) 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 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 "Start Upgrade". DO Non unplug your router or click annihilation else in the concurrently; let the upgrade consummate!
  7. Wait 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 at present the upload speed is fast too, at 11 Mb/s, or nearly 70x faster than what it was earlier. Woohoo!

I hope you found the mail helpful. If your router has a different firmware upgrade process, go out a annotate with the steps you followed and then others can find information technology. Happy web browsing!
