    Hello,

    For a week or so I bought a wifi router from my internet operator and since then,the wifi network says "no internet access".
    I called the internet provider and they said that it's from my computer and that everything is fine from the company's side.
    My laptop is a Dell inspiron 1525.
    I tried entering at Ipv4 connectivity the i.p. addresses from ipconfig and nds servers from several forums,but no result.
    I disabled homegroup,tried disabling windows firewall,updated the dell wlan driver,still nothing.
    What should I do?

    Have you set your pc to use DHCP - that is to get the IP address and DNS server address automatically from the router?

    Hello and welcome to the forums.
    I have no idea if this will help you at all or not but you can give it a try and see, it actually only works with certain Dell wireless cards that use a Broadcom chipset
    Evidently the driver (new versions) default to setting the "BSS Mode" to 802.11n and some have found that changing that setting to 802.11g has resolved their issues. So....
    Go back into device manager
    expand network adapters
    select then right click the problem wireless adapter and choose properties
    select the "Advanced" tab at the top
    In the left column titled "Property:" see if you have a BSS Mode listed. If so select it and in the right column titled "Value:" use the drop down arrow to change from 802.11n to 802.11g
    OK your way back out of there and reboot and see if that helps.
    Regards
    Randy

    Is this on the router? If so then this means that the router will respond to DHCP requests from the pc but then the pc must be set up to make DHCP requests. Have you got the properties of your network adapter on your pc set to do that? Goto control panel, network and internet, network and sharing centre, change adapter settings, right click on the wireless network connection, select properties, click on internet protocol version 4, click on properties. Check that "obtain an ip address automatically" and "obtain dns server address automatically" are both checked.

    @patcooke they are both checked.
    @Trouble I have some modes that are called: IBSS 54g(tm) Mode set on "802.11b Only" and IBSS 54g(tm) Protection Mode set on Auto.

    Can you confirm that your laptop does work now, elsewhere, local hotspots (library, coffeeshop, McDonalds, etc.,)??
    If so it would seem to refute your ISP's claim that there is no problem with their device.
    Can you provide the results from typing
    ipconfig /all
    into a command prompt, so we can have a look at what you are getting in the way of an IP address schema, if anything?
    Can you ping other network nodes (other computers, inside edge of you router)? Can you ping 64.233.169.99 ?
    Can you ping "www.google.com"?

    OK, well the information you provided pretty much explains everything
    Taking the time to test your laptop in another environment (public wifi hotspot) might help advance the diagnostic process.
    Not knowing the specifics regarding the Wireless? Router you've purchased from your ISP, I can't make any suggestions regarding the configuration except to suggest that you attempt to experiment with a different channel (3, 6, 9, 11) on the router combined with perhaps altering the present wireless security settings, even temporarily running it open (none) for testing.
    Without knowing specifically which driver you are currently using I can only suggest;
    Use Internet Explorer and go here Microsoft Update Catalog
    There are four drivers located on that page, two for 64bit Win7 and two for 32bit Win7, Microsoft Drivers as well as Broadcom, make sure you obtain both for your particular architecture and try either and or both by forcing an install through device manager by uninstalling the current install (including drivers) and then manually update the driver by browsing to the folder where you have downloaded and extracted the drivers above. See if either of those provide any better results.
    It's rare that I would suggest using the Microsoft Update Catalog to resolve driver issues but in some cases, while not always optimal, they will at least support basic functions of legacy hardware and since the latest Dell Driver that I can find references Windows XP
    this may be your only option, short of purchasing a USB Wireless Network Adapter.
    What does Device Manager have to say about your currently installed hardware (all)? Any error symbols? It may be necessary to visit Dell's website for the latest drivers (for Windows 7) for supporting hardware (Chipset, BIOS, etc.,) in order to get dependent hardware devices to work.
    Good luck and keep us posted.
    Regards
    Randy
