Hi guys,

I've been researching and trying to days to get this to work with no avail so I decided to post here for some help as I see this community is really active.

We've got 4 different laptops here and none of them can connect to the wifi anymore (it suddenly stopped working for the last whole week). We can connect to the internet through ethernet cables though. We only use one at a time (if ethernet, then wireless is disabled and vice versa).

Here is a copy of the ipconfig/all:

You have an IP on your LAN, but none on your wifi. Check your router to make sure DHCP for wifi is turned on and you have enough available addresses.

Disable the Ethernet if you want WiFi and disable WiFi if you want wired ethernet - - you can only One or the other but not BOTH ad the same time.

Hey peterm777. Sounds like a router gone bad to me. I would power off all the pc's, then reset the router to factory specs. See if you can connect wirelessly to the default SSID of the router. If you can't, see if there is a firmware upgrade for your router. The firmware upgrade process only takes a few minutes and the process is not difficult if followed correctly. I had an older Linksys that the client and her ISP rep said was bad, and when I looked at it,it sure appeared dead. I had nothing to lose so I downloaded a firmware upgrade and applied it. It worked in both modes after that, so I secured it and haven't heard from her since (over a year).

Hey guys, thanks for getting back to me.

I could only get on the net using the ethernet cable at the time and I checked the wifi to make sure there is enough available addresses for the DHCP.

Disable the Ethernet if you want WiFi and disable WiFi if you want wired ethernet - - you can only One or the other but not BOTH ad the same time.
I've tried that and still the same problem

It seems that I may have a bad router, I'm not too sure. The router is a Netcomm NB304N, I did a firmware update and reset the router to factory specs. I then tried to connect to the default SSID and had problems with it initially but after a few attempts it worked for a bit and then stopped working.

Another weird issue is that when I'm connected via ethernet cable only and wifi is disabled it still shows a yellow exclamation mark even though I can connect to the internet. In the diagnostic tests everything is a pass except for this:

Test ATM OAM F5 segment ping fail

Any thoughts?

I would go for a new router (or maybe borrow one for an hour or so, I have seen a few fail). 4 pc's that lose connection is not a problem with the pc's, especially if it will work using Ethernet but no wireless connectivity on either machine. You could lose a wireless signal and the pc could still show you as being connected to your SSID, but a balloon with your cursor over your wireless icon should show no internet access.

I am facing the same issue...can someone please tell me how can I disable the Ethernet because I want use my WIFI

Hey OmkarPad. To use a Wi-Fi connection instead of using a "wired" (Ethernet) connection, just disconnect the Ethernet cable from the pc and allow the pc to view the available wireless network you want, then connect.

What do you mean by a secure connection, I don't understand..how do I know if the connection is secure or not? sometimes the wifi won't work on my mobile as well..is there something wrong with my wifi router? this is just a maze for me ...

I hope this will help you to solve my issue...I was connected to the wifi this time but after sometime or once when I restart the laptop I won't stay connected.

When you first got the router, or at any time since, was it setup by someone to secure it where a name was given to your network and a password was created that you had to enter to be able to access your wireless network? That is what"s called securing your network
When you hold your cursor over your wireless icon in the system tray in the lower right corner< what is the name of the network shown?

I disagree. We had both Wifi and Ethernet at the same time when this new HOMEDSL was installed. After a month, the Wifi just disappeared.

I recently had this issue where if I connected a certain desktop PC to the residential gateway (an NVG510 from AT+T) via ethernet, all wi-fi connections hang. You can see the SSID but it won't accept correct wi-fi passwords and won't connect to the internet. However, ethernet wired connection works. When I disable ethernet or unplug ethernet from this particular desktop PC, all wi-fi connections work again. After 2 AT+T technicians were sent out, no one could solve the issue. I posted the problem online and someone suggested I try disabling IPv6 in the NVG510 residential gateway's settings. I did and everything works again, both ethernet and wireless. It has also been stable instead of dropping every few hours/days like before.

Doing some CMD prompt instructions based on typing "Netsh" and then some command to reset things related to the adapter etc. have apparently solved the issue. Someone posted a Youtube video describing how it's done. Doing some of these seemed to have worked to fix this issue:

Hello Tech Gurus
Thanks for your support for the ammatures present company included =)

Can some shed some light on this...I have a different issue but on the same lines

My lappy accepter direct ethernet connection service...but stopped accepting the wifi signal

Test processes so far as follows

Direct connection from wall modem - check
Direct connection from router - check

Each time I attempt to connect to wifi after each test it works for less than 60 seconds then switches off

Reset modem on wall -check
Reboot router - check
Reboot lappy - check
Restore point - check
Updated nic drivers - check
Running w7p updated - check
All other devices in the house using wifi work without issue - check...it just my lappy that is having this issue all of a sudden I might add

I asked a friend who is quite knowledgable in IT and he said it was wifi hardware suds (what are suds?)...can anyone confirm...explain in simple terms and or please provide a solution

*running w7p
Dell Latitude E6500
NBN 100Mbps
Modem NF17ACV

Important point is all other devices work on wifi...approx 10...have no issues...including phones...kodi box...just my laptop

Thanks in advance

Typically, we look for a newer WiFi driver - - NOT from Microsoft but directly from the chip maker.
Look for the make/model that fits your version of Windows.
