    You have to configure both your AP and your router. Both should have IPs on the same network, but the AP's must be static. I don't think your router will accept an address outside the DHCP range, so you'll have to reserve one within.

    Since you said you set the router's address back, the AP should be visible to it (but it's address has sinced changed).

    Connect the AP and some computer to the router's LAN ports.
    Open a command prompt window. Type IPCONFIG and use the Default Gateway address to browse to your router's configuration page.
    Go to Setup (Top) / Network Settings (Left)
    Verify that your computer and the AP appear in the Number of Dynamic DHCP Clients table.

    If they don't, stop right there and tell me.

    Click on Reserve at the end of the line showing your AP in the table. Verify an address reservation has effectively been made for it.

    In the router configuration tab, click on Save Settings.

    Browse (in a new tab) to the AP configuration page using the IP address you've just reserved (You said that you knew the credentials). Make a note of:
    The 802.11 Mode option (N, G, B)
    The SSID
    The channel number if not set to auto.
    Since I don't know your AP, you'll have to find out where to go by yourself.

    In the router configuration browser tab, go to Setup (top) / Wireless Settings (left).

    Check that the 802.11 Mode option is the same as/compatible with your AP's.

    Enable Auto Channel Scan: No on both devices.

    Wireless channel: Ensure channel separation by using a different one for the router and the AP. 6 for the router and 1 or 11 for the AP are common in NorthAm. If you live in a WiFi crowded neighbourhood, you should ideally use some site-survey software to select the less crowded, or showing the weaker signals, channels.

    Wireless Network Name: Using the same SSID is better for seamless roaming, but most wireless clients tend to stick with the first AP they find. Your security settings should then be the same on both devices.
    With different SSIDs you can select the one you want to connect to. Moreover you should see both the AP and your wireless router in the list of available connections.
    Even if you don't have to here, I'd suggest to keep the same security settings on both devices.

    Wireless Security Settings: Security mode and passphrase must be set on both devices.

    Do not forget to save settings before leaving a page.

    Before leaving, ensure that you've changed the password from the default to access each device, and save the configuration in a file (Tools / System).

    Save and reboot (Tools / System / Reboot).

    Restart every device wired to the router and the AP.
    Check the configurations by browsing to them (You'll have to enter the credentials again).
    Try connecting wirelessly to the AP using the SSID and passphrase you set.

    Since Canadians are known to be good with apologies :), I hope you'll accept mines for creating such a mess by telling you to reset instead of reboot your router. I guess drinking and browsing don't go well together.

    Et voila, you're now ready to buy a new router and do it all over again (except for the AP part)....

    Let's hope the homegroup is now fully functional. Who knows?

    P.S. Don't throw away the D-Link. You can always use it as backup or as an AP, a range extender or a switch.

    This morning I deleted the Homegroup. It took me a while to figure out how and most of the info came from
    Cannont Delete or Modify Homegroup in Windows 10 - Microsoft Community
    For future readers of this thread:
    On ALL computers go to Control Panel>HomeGroup, click Leave the homegroup and follow the instructions. Turn off all but the one that the Homegroup was started on (VERY IMPORTANT: ALL OF THEM), then go to
    C\Windows\ServicesProfiles\LocalService\AppData\Roaming\PeerNetworking and delete all idstore files, then restart it and confirm that the Homegroup is gone.
    In theory you shouldn't need to check but I did and the Homegroup was still there. After I tried again I noticed that someone else turned a computer on, which prevented it from working. After that one was turned off it worked perfectly.

    Next I tried starting a new Homegroup on a different computer but the 5720Z didn't see that one either so I deleted it and turned that computer off.

    Finally I started a new Homegroup on the 5720Z which all of the other computers have all joined successfully.

    As for the AP:
    I can still access it from the bookmark so I have the IP address and the MAC address, which is good because I can't physically access it to read any stickers it might have without moving a lot of stuff. Its webpage looks very generic to me; I can't find anything there to say what model it is or who made it.

    Open a command prompt window. Type IPCONFIG and use the Default Gateway address to browse to your router's configuration page.
    Is it OK if I just open the router's webpage from the bookmark? All of the computers are in the list plus teh network drive and a couple that don't have names (I suspect that one is the TV). None of the addresses match the AP so I am stopping right here and telling you.

    BTW: No need to apologize. I have learned a bunch of stuff that will help me in the future and it was worthwhile knowing that the router wasn't the problem.

    I was referring to an old show on This Hour Has 22 Minutes titled Canadians are always apologizing! :) Thank you.

    Glad the Homegroup issue was solved.

    Please give me:
    The AP's IP from your bookmark
    The router's IP and the DHCP range

    Open a command prompt window and type:
    PING xxx.xxx.x.xxx where x 's represent your AP address
    TRACERT xxx.xxx.x.xxx

    PING xxx.xxx.x.xxx >C:\Ping.txt
    TRACERT xxx.xxx.x.xxx >C:\Trace.txt

    And post the two above text files.

    More trouble: I just remembered I had saved an article (see
    http://www.dslreports.com/shownews/B...Routers-126213) in which your router is mentioned.
    You must:
    Change your password from the default (I hope that's done) and check that remote administration is disabled.
    Save the configuration.

    Then when you'll have time:
    Update the router's firmware if you don't run the latest version.
    (Tools / Firmware / Check Online Now for Latest... )
    Heed the warning and plug your router into a UPS if you can.
    Download the file with your browser
    Upload: Browse to where you DL'd the file
    Click on Upload button

    When I tried PING xxx.xxx.x.xxx >C:\Ping.txt and TRACERT xxx.xxx.x.xxx >C:\Trace.txt it said "Access is Denied."

    Is this OK? I copied & pasted from the CMD window...

    Re router settings: Yes, the password is changed and yes enable remote admin is unchecked.

    I think I'll wait a few days and see if I replace the router before I update its firmware.

    Thanks again for all this help.

    AP's IP: 192.168.1.11
    DCHP Range: 192.168.1.100 to 192.168.1.199
    The AP's IP is outside of the DHCP range so it will never appear in the router's tables. That was the old way to do things before reservations were introduced. I don't see any problem with that, since the router will never change the AP IP address.

    So skip the reservation altogether an proceed as follows:

    Browse (in a new tab) to the AP configuration page using the IP address you've just reserved (You said that you knew the credentials). Make a note of:
    The 802.11 Mode option (N, G, B)
    The SSID
    The channel number if not set to auto.
    Since I don't know your AP, you'll have to find out where to go by yourself.

    In the router configuration browser tab, go to Setup (top) / Wireless Settings (left).

    Check that the 802.11 Mode option is the same as/compatible with your AP's.

    Enable Auto Channel Scan: No on both devices.

If you live in a WiFi crowded neighbourhood, you should ideally use some site-survey software to select the less crowded, or showing the weaker signals, channels.

    Save and reboot (Tools / System / Reboot).

    Restart every device wired to the router and the AP.
    Check the configurations by browsing to them (You'll have to enter the credentials again).
    Try connecting wirelessly to the AP using the SSID and passphrase you set.
    And your Homegroup will be fully functional.

    Please don't forget to mark the thread as solved when you'll have exhausted all your questions on the topic.

    Thank you and good luck.

    OK, I finally have time to get back to this.

    The AP says its Mode is AP. Other options are 2 kinds of station, 3 kinds of AP bridge and Universal Repeater.
    Its Band is set to 2.4 Ghz (B+G). Other options are 2.4 Ghz (b) and 2.4 Ghz (G). (Don't you love it when they use the same term for something else?

    ESSID is our network name followed by AP

    Router 's mode is set to Mixed 802.11n, 802.11g and 802.11b

    Enable Auto Chanel Scan is now turned off in router I can't find that setting in the AP. The AP was set to Chanel 11 and the router to Chanel 6 so I left them alone.

    We have always seen both the router and the AP in available connections list so I left them with the names they have always had.

    Security: AP says WPA pre shared key, cipher WPA(TKIP). Router says WPA-Personal, cipher TKIP and AES. Pre-Shared Keys match. Should the ciphers be set the same?

    I will now reboot everything. I will let you know if I can connect to the AP soon.

    Should the ciphers be set the same?
    Since you have distinct SSIDs, you don't have to keep the same security settings.

    If you have issues connecting, unplug your router from the internet modem (to be safe) and disable security on the device (AP or router). If you can then connect, the problem is in your security settings. For example, some devices weren't WPA2 capable.

    Everything connected automatically and I didn't have to log into the router on either Ethernet or Wi-Fi. When I try to connect to the AP wirelessly I get "Can't connect to that network".

    I must have accidentally changed something in the AP's settings without noticing because now when I try to access through my browser from the IP address I get
    "Access Error: Unauthorized when trying to obtain Access to this document requires a User ID"

    Since the Homegroup is working I'm going to mark this as solved. If you know of anything quick & simple that might regain access to the AP I am willing to try but otherwise I think I'm going to give up on it. We don't really need the AP anymore anyway. We installed it because my old laptop was having trouble connecting to the router but I haven't had that laptop for years and everything we have now seems to connect to the router itself well enough. Except when the router itself gets flaky. I have been having to re-boot it via the power supply every week or 2 lately (the main reason I am thinking about replacing it). Who knows, maybe resetting it will have fixed that If not they aren't that expensive and this one has had a relatively long life.....

    The only other network problem I'm having now is that the TV has started refusing to accept the Ethernet connection but it connects to the Wi-Fi as soon as I unplug the Ethernet cable so perhaps there is a problem with the actual cable. We will be re-arranging the entertainment stuff soon and I should be able to check for that then. Or I might just leave it on Wi-Fi because it seems to work just as well that way.

    Again, thanks for all your help with this.
