Lose the wireless connection when the modem connects to the internet.

Hello

I've updated my laptop to windows 7 (new installation).  I have a cable modem which is connected by ethernet to a wireless modem/router which I have configured to be a wireless access point (dhcp is the cable modem).  The laptop can connect wireless access point when the cable modem is not connected to the internet (so the ip address of the access point is 192.168.100.50 & the laptop takes an automatic ip address within the range). The problem is when I connect the modem cable to the internet, & so the ip address of the access point is derived the cable modem, the laptop can't connect to the access point. When I renew the ip address of the wireless card, it says it is connected to the selected network but the ip address is not correct, nor do I have access to the internet.

The laptop connects fine to pick up the new ip address when it is ethernet connected the access point when the cable modem is both on or off, so I can access the local access point configuration when the modem cable is off, & can access the internet when the cable modem is enabled. When it is connected with the cable modem access point wireless at sea, both my wireless & ethernet connection say that they are connected to the selected network, but as soon as I turn on the cable modem, wireless connection says it is connected to an unidentified network, but my ethernet connection is connected to the selected network.

I tried the broadcasting/no broadcast of the SSID, different levels of security, modification of the power saving options on the card wireless without success. I don't think it's a problem with the real network that the wireless card can capture the network & settings when the cable modem is disabled.

This Setup has worked well when I had win xp.  My mobile phone can capture the network without wire end also & is able to access the internet.  The driver for the wireless card is current as well as the firmware on the access point.

Can you please help? Thank you very much

Hi Jack

You led me in the right direction with the MAC addresses on the cable modem.  It's a simple solution... turn off the cable modem so it would refresh the MAC addresses of connecting devices, & hey presto, I wireless & ethernet access internet on my laptop with wireless internet on my laptop.

Thank you for your perseverance.

See you soon

    Original title: Network question

    Hello
    I noticed a change in my system. My wireless connection says "no internet access. The other connection, presumably one wired, is OK.
    I have no problem on internet and computer my son who is temporarily connected to the same router is also online.
    But I wonder what can happen to change that, and what I can do about it. I noticed this when a little yellow exclamation point appears on the network icon in the systray /taskbar.

    I spent a lot of time with the guidance of the internet, Cisco install CD, ipconfig and its switches, update drivers for the network adapters, uninstall the card network wireless and relocation, etc.. But the situation remains the same.

    I will link to some images what I mean (hope it works).

  • I lose the internet connection randomly but never lose my wireless network connection.

    I use a hp pavilion dv9500 with 64-bit vista sp2 and built in a wireless adapter that will fall randomly my internet wireless connection, but maintains my wireless network connection with an excellent signal strength.

    My (non-permanent) fixed
    I know how to reconnect to the internet, but it forces me to diagnose a repair my connection. It then displays "cannot connect to Server primary dns (75.75.75.75)"after which it gives "things to try" who never work and a button 'Reset the ip address' that I click. " repair bar will fill up to half way and go to a new screen solution that shows more 'solutions' and a "reset wireless adapter" button which I click. the remedy bar will fill and then display windows can not solve the problem and go for help. I then manually disconnect from the wireless network and my computer will automatically reconnect to the network and to the internet. It takes about five minutes to fix, but it happens so often that it is getting boring. The process will not work if I only to reset the ip address and then disconnect from the network, only to reset the wireless adapter and then disconnect, or just disconnect from the network and reconnect. I have to reset the ip address and the wireless adapter and then disconnect from the network.

    The internet connection will tend to disconnect when I watch a lot of youtube videos, when I download large files like a game on steam, or just just randomly when I use it. I'll use it for a long time and he can't let it go, but sometimes it will go down to ten minutes after I had just reconnected in a drop-down list. It happens randomly without another warning that download time will increase from 2 mb to 50 k in two seconds all about or stop the loading of a youtube video when I look at it.
    I searched everywhere for an answer, but it's as if it were a new problem for all humanity or just im the only person who does not know how to solve this problem, because there are no forums or FAQ not related to my problem. It is not so much a serious problem such as an irritating problem that appears at inconvenient times or when I just want to relax and watch a video. It takes some time to reconnect and even though I know how it would be better if my connection would just stay connected to the internet at any time.
    I have no idea what the problem could be that whenever I have find I never get related problems. all advice or solution would be great.
    I also share this modem with other three commonly used computers: a wired office and two other laptops that the two are connected wirelessly. both other laptops do not have the same problem as mine. My router is a linksys e3000 wireless router.

  • Problem WiFi on Satellite Pro C660-2TQ - lose the internet connection

    Hey people,

    hope you could help me. I did a new clean install of Win7 (32 bit) on my Toshiba Sat, C660-2TQ.

    His job very well, except one thing:
    the adapter Realtek RTL8188CE-in my laptop is just terrible...

    I installed the latest driver for this Home Premium wifi, but I lose the conn. to the internet all the time.
    While I have to disconnect in the bottom right corner my laptop and connect again manually.
    I have to do this every minute or so and its very annoying.

    I saw read several discussions about the problems with this specific wifi adapter, but no solution has helped me...

    I didn't install all the listed drivers (34 available for me) but then what I Normand to update my BIOS or would it be a driver as the driver for the touchpad is necessary to get my wifi working properly?

    Hope you guys could help me...

    honestly desperate

    cordially :)

    Hello

    WiFi disconnection problems have different causes and its not easy to say why it happens.
    So, you will need to check each step and each option.

    First of all, you will get the latest version of the driver for this adapter WLan on the Realtek driver page:
    [Download driver Realtek RTL8188CE | http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level= 5 & Conn = 4 & DownTypeID = 3 & GetDown = false & downloads = EU tr]

    Would recommend that you do not install this driver.
    Before you begin with the installation, uninstall the previous driver.

    Secondly: it would be possible that this issue isn't related WLan driver and update the driver wouldn't help you much. In this case you should check the other parameters.
    I recommend you to check the router settings and test different standards WLan (802.11 B / G or N).

    In many cases, the problems of compatibility between the router and wireless network card could lead to similar to your question.
    Of course, you should also go to Device Manager-> card WLan-> properties-> Advanced tab
    and must check if you can switch between the WLan standards singles (802.11 B / G or N)
    Power management also in tab (last tab) you must unselect the option to turn off the device to save power.

    What do you mean by "information"?
     
    What do you mean by "just not my router? Do you mean that you do not have
    see same SSID of your own router (network name) in the list of available
    wireless networks? If so, connect to your router with an Ethernet cable,
    Enter the router configuration utility and make sure that the SSID
    broadcast is set to 'enable '. If your router is already configured to
    broadcast its SSID, and you don't see it well be able to see the other
    near wireless networks, the portion of your router wireless is
    cut or broken.
     
    Generally, symptoms such as you describe are caused by a defect of
    to authenticate to the router, usually due to a mismatched
    password encryption.
