Laptop freezes when connected to internet via WiFi

I use the laptop Dell inspiron 15r, with Windows 7 ultimate on it. Whenever I connect to the internet via WiFi, after a while, most of the programs I use freezes, and the internet connection is cut off. The same control panel functions do not occur. Also is not possible the normal closing, and I have to force close down at length by pressing the power button. This situation arises that if I use the WiFi. When I use a LAN cable, no problem. This situation is quite irritating, like many times I have no other choice than to use a wi - fi connection and whenever I use it after a few minutes, I have to restart with force, and the cycle repeats. Please suggest a solution. Thank you.

Hello Brad,

I tried the thing of diagnosis, but could not get anything out of it. The problem is now solved because I updated the drivers of network on the Dell site, but currently I am confronted with some problems, that I used to.

Thank you much for the help.

Kind regards

Sunil.

  • BDP-S570 - does not connect to internet via wifi

    I just bought this today and it does not connect to the internet via wi - fi. I'm entering properly (my iphone, ipad and computers connect very well). I called tech support and they had no idea what either. I then connected with an ethernet cable, updated to the latest firmware and tried again with no luck. Does anyone have any suggestions? It shows that the wireless is OK, but Internet Access - failed. When I return to the guests and have it analyzed the available networks, it shows that I am connected... something is weird. I'm back if I can't make it work in the next day or so.

    Network problems can certainly be difficult to diagnose.
    Here are some useful steps to check where your problem is.

    Check the IP address: is it 192.168.x.xx? or 169.xxx.x.xx
    If you have an address 169 it is a fake connect.

    What kind of network do you have? It's a Modem/Router combo? This is a modem connected to a router and then your Blu - ray player.

    the router/Modem combos are more complicated, and you need to consult your provider of Internet services (ISP) to connect to help. (maybe a MAC filtering problem?)

    If you have a problem with your Modem/Router try get a router and connect to the modem, you can have the best success with a stand-alone router you will have with a handset as they are less complicated to use.
    If you already use a stand alone, try to temporarily disable your security and test it without warranty.

    is the firmware updated on your router (not the S70 but the router) the latest firmware is sometimes useful.

    Best regards

  • Satellite P100: How to connect to internet via WiFi?

    I read a post above that says that the sticker on the bottom of the laptop ' wireless network: no w/l ' means that there are no installed wireless.
    I'm fairly certain that my Satellite P100 has installed. I customized my phone, ensuring that I have added wireless for the school.

    I have an on-off switch for the wireless on the case. Also, when I entered a zone wireless for the first time, a program (Q-Connect) came.
    I reinstalled Windows XP and wonder if it is a software that is missing (which has been the case with other similar programs audio).

    This could be the operator error?

    How to connect to wireless internet?

    Hello

    First, you must be sure that your laptop has WLan card to 100%. Go to the Device Manager and check the network adapters section. If you will see card WLan (intel or atheros) then you unit definitely has the Wlan card.
    To use the WiFi network, you must configure your Wlan router. Consult the manual.
    You must then activate the Wlan switch on the side of the laptop and use the combination FN + F8 to select the WiFi network.

    For the other steps, you can also check this forum wireless. Here you will find a lot of descriptions.

  • Unable to connect to internet via WiFi

    Thanks & best regards,

    Say hello to new raj_sach.

    You have to call Comcast and ask another router.  This model is known to have many questions.

    If you take a look at the job for the router (click here), you can see that it supports up to Windows 7.  This means that all users on Windows 8 will have an update of the firmware (even if you have Windows 7, I wanted to report it).  ARRIS published an update that solves a number of problems with this router - but it will not work on the version you get from Comcast.  This means that Comcast will have to release their own update to solve problems.  You can see on this site on the site of Comcast that this router is known to have problems.

    You can see similar problems in this article and this thread.

    Contact Comcast immediately and ask for a new router.

    Have a great day!
