WRT 400n lost internet

I have been using my wrt400n(v1.0.01 B19) for several months now, and with the exception of the security set and get the "n" to run it worked fine until this morning.   Woman woke up before me, connected to facebook/farmville, etc. and was running.  When I woke up and tried to connect to the internet, it wouldn't connect.  I get the network local but not the internet.  Tried resetting, control the installation program, net magic fix pro, any and all I could think about.  I know that it's the router because I plugged the modem directly to my laptop and it ran and then I reinstalled my old wrt54g (all the same settings except net name) and it is what I use now.  I have swapped the cables, Redid the installation and ran NMP set several times and still not connect to internet.  A minuite it worked, the other, it is not but it works with the local network (3 wireless(2 'n'), 1 e - adapt (n), 1 printer, and 2 computers connected.)

Any ideas? I'm at a loss

Thank you

Open the router configuration page and date settings on the router and check it out... Reduce the MTU value to 1350 and click on save settings... under the wireless tab, click Advanced Wireless settings... Change the tag to 50 interval, change the Fragmentation threshold to 2304, change the RTS threshold to 2304 and click on save settings...

Power cycle the router and check the connection...

  • How to optimize the WRT 400n for Internet TV

    I've been using a WRT 400n for awhile with 2 pc... a tower near him and a computer laptop about 50 ft, in another room. As much, I would say I am only using the 2.4 GHz to channel 11 band.

    We have just added a Sony Bravia HD TV and a Sony Blu - ray player VD (which is really, as far as I can see, a cool internet access device which can read the DVD). Favorite use is to watch TV shows and movies from Amazon. Problem is, the streaming is very uneven and sometimes what Amazon calls 'connection speed' (which I think is really the network bandwidth) gets so low that the buffering will fail and lose us everything we see.

    So, my question is, how to optimize?

    1. Can I configure the WRT 400n somehow so that the TV / DVD device combination uses 5.0 GHz and this could help. If this is the best option, where can I find detailed advice?
    2. Y at - it than available th firmware update might help?
    3. Could I consider an access point or a Repeater?
    4. Should I go for a router upgraded?
    5. Displacement of the top would REALLY help? I am very reluctant to do this - it is a major concern, but if it's the only option...

    As you can tell, I am naïve in these things and would really appreciate wise counsel!

    Thank you.

    1. the recommendation mentions of connection speeds, for example 10 Mbps. This has nothing to with the frequency band use for a Wi - Fi connection.

    2. the specifications for the BDP-S780 says: ' Wi - Fi built in: 802.11 b/g/n. It does not support the band 5 GHz. 5 GHz band is not an option.

    3 once again: the best solution is to ethernet wiring.

  • Lost internet connection - rogue app?

    Hi, I have downloaded a widget to toggle 3G last night and tried it out. It did not work so I uninstalled, but now I find that my phone is now more able to get an internet connection - it seemed have lost internet connection as soon as I typed on the widget.

    Is it possible that the app screwed up my phone this way, or is there another explanation (I'm trying to discover my carrier right now if the network declined - I can still send and receive text messages)?

    I have to reset my phone?

    Too bad. My career has simply returned internet settings on my phone and now it works again.

    So... WHY

    And... WHAT can I do to keep my internet/network connection when my new MacBook Pro 15 alongside other computers?

    -When the internet is down I am connected to the router (wired and wireless, the connection is not lost / disconnected cable...).

    Well try the following steps:

    1] open the browser and in the address bar type 192.168.1.1 which will open the router configuration page.

    [2] lower the MTU (Maximum Transmission Unit) of 1500 to 1400 or less (usually found on the main page / basic configuration of your router)

    [3] then go to the Wireless tab, leave network as mixed mode and make the bandwidth of 20 MHz only and channel 9...

    Settings wireless #Adjust the following:

    ~ ~ Reduced from 100 to 75 beacon interval

    ~ ~ Lower the threshold of fragmentation of 2346 to 2306

    ~ ~ Lower 2347 to 2304 RTS threshold

    Then check the status of the connectivity...

    Restart your router, your computer and power cycle the device you want to
    "Play to." probable IP changed on your network addresses.
     
    What you play in? do you target the device in the network window
    After the restart, etc.?
