    WiFi is VERY unreliable


    My laptop's wifi does not work most of the time.


    • The power led is on
    • WiFi status shows I'm connected, at 3/5 strength in my usual location.


    When I check the task manager, it'll download at roughly 30mbps for half a minute, and then the next hour it just sits there at 0kbps. Often, turning off wifi (for example, airplane mode) and back on will repeat the cycle, where it seems to work just fine for half a minute, and then flat out stops. It stays at 0kbps, occasionally jumping to a whopping 8kbps. I'd rather be on dialup.

    The store has diagnosed the laptop and found no problems with the internal adapter.

    So one of the things I eventually did was taking the wireless adapter from one of my other computers and plugging it in. It worked. After days of frustration, I figured: "Whatever. I'll just use this adapter since the other PC is basically a dust collector at this point". Fast-forward a few months and I'm back to where I started: for some reason my external adapter is now giving me the middle finger and I'm having the *exact* same issues now.

    For example, I go to youtube and start watching a video in 1080p.

    Works fine, buffers the first half minute, and then it's over. Nothing. No youtube, no mail, nothing. I'm not even getting local firefox error pages (the typical "connection failed" message) but the spinner just keeps spinning indefinitely.
    I took this screenshot right after the problems started. The next hour it came back "online" once for about 5 minutes, before going back to "sleep".

    The external adapter comes with 2 leds: a "link" led that is continuously on, and an "active" led that blinks when I'm actually using the network. It is interesting to note that when I'm having these issues (which is 90% of the time), the link led remains on, while the active led stops blinking.
    Combined with the fact the store does not find anything wrong with the adapter and I'm absolutely positive the external adapter works, this leads me to believe something else (windows 8?) is preventing the adapter from working correctly.

    Some statistics:
    • Toshiba Laptop
    • Windows 8.1
    • i5-3230M CPU @ 2.60 Ghz
    • 6 GB Memory
    • Internal adapter: Realtek RTL8723AE Wireless LAN 802.11n PCI-E
    • External adapter: D-Link AirPlus G DWL-G122


    Modem/Router:
    B-box 3 - Belgacom
    Unfortunately this crap has been forced on me by my ISP, and their line of modems are the only devices authorized to provide digital TV. The only thing I *could* try do is put a different router in front of it to take care of the in-house wifi, but besides the fact that's just a stupid setup, I don't simply have 1 lying around right now. Might still try it though, but not in the immediate future.

    Things I've tried:


    • Yes, I've gone through the basic troubleshooters. As far as windows is concerned, everything is perfectly fine.
    • It's not the internet. I have 3 other computers at home (all on windows 7) and everything is perfectly fine with downloads up to 30mbps. I can easily watch HD youtube on all 3 devices simultaneously. Additionally, my ISP provides digital TV (basically glorified internet) which works just fine.
    • Ethernet works. But barring the fact that it's a new-ish laptop and this stuff is SUPPOSED TO WORK, ethernet is simply not a workable option in my situation.
    • Signal strength doesn't seem to be the issue. 5/5 when sitting right next to the modem and it still fails.
    • External adapter now has the same issues...
    • Countless little things like disabling firewalls, putting the modem into b/g mode (previously b/g/n), etc... Eventually, you get so desperate you'll try anything.

    First: Is the wifi router yours or do you connect to some network?
    Lease for an hour is very low. It seems like a public's wifi limitation?

    The router is mine: B-box 3 - Belgacom

    3600 seconds seems to be the default lease time. I could increase it if you think it'll help...

    OK, for starters try changing DNS, it is actually always a good idea to use better DNS than ISP's.

    https://support.opendns.com/entries/...-Configuration

    Secondly: try disabling IPv6, it actually does not work that well at all, so it might be causing the problem.

    Disable IPv6 | Windows 8

    Third: most of the problems with wifi can be solved by disabling DHCP and setting up everything manually.
    So unless you travel with your notebook, this might be the best option. It is annoying, but it usually works.

    Check if your router support to set up a lease forever, if not you might need to disable it / that DHCP thingy.
    Then you will just add all the info, you have already set up DNS and disabled IPv6, so just 3 more entries.

    1. Already tried, it's currently set to google's.
    2. Already tried, it's currently disabled again.
    3. Lease forever isn't possible. I can try disabling DHCP just to see if it helps, but it's far from an optimal solution. Long-term, I don't want to change IP settings every day.

    If disabling DHCP would work, there is a lot of software, which allows you to change it fast:

    So that didn't help either.

    I had DHCP disabled for 1 hour and had the exact same issues for the entire hour, so clearly it didn't help.
    I now have a 24h lease time but still not helping.

    Are you driver's up to date? Did you upgrade to Windows 8.1 or was it preinstalled? I would try and update your drivers for your wireless adapter. I had a bunch of issues after upgrading to Windows 8.1 with wireless adapter as well. I ended up downloading a driver update program that updated my wireless adapter and it's been working fine. I was also told that most drivers that were preinstalled with Windows 7 ( If you upgraded) are not compatible with Windows 8.1. I hope I'm on the right page with you.
