You say you have other (older…) laptops/PCs that can see and connect to your router…; and "nothing" has changed re' the router...

Using one (preferably two) of the working systems as reference: check the settings on the working system(s) carefully - step by step. Duplicate each setting (step by step) on one of the new laptops.When you are "sure" the new laptop is set up as per a working model - see if the new laptop can finally see the router?

Long shots… - very long shots… - especially as you say in your post-2 that you have managed to another hp 650 laptop successfully (and it hasn't been on the network before???)

Are you broadcasting the router SSID etc.? Or was your router configured to hide that… Often when it's hidden (an option in the router's wifi set up), folks forget they have done that - after having successfully configured laptops/PCs various manually to find and connect that (now concealed) SSID… If it's hidden/concealed.. I don't think unauthorised kit will see it… That kit has to have the SSID entered manually.

Ensure (check carefully) that the new laptops are all using the same channel as the router is broadcasting on…; same wifi protocols etc… that other working kit is using… Who knows...?

To have three laptops with the same problem is unusual - if thinking in terms of the laptops being faulty..; but obviously not impossible… And that they can see other networks OK does point to something nearer home; router setting (SSID hidden for example - as above).

Even if you have MAC filtering and manually assigned ip addresses set up, and the router "is" broadcasting the SSID - you would be able to see it at least; but not connect… MAC filtering - when enabled - allows two options when invoked: allow only those listed to have access, and the other disallows access to those listed.

Similarly without the appropriate 'key" even if you can see a network (the SSID is being broadcast) and it is using an encrypted "key" to control access, you ought to be able to see it but not connect (without correct "key").

Three laptops failing are a fat chance.
Problem is most likely with the router settings.
Which router are you using? Is the wireless network configured?
Have you ever managed to connect to this network before?

i have managed to connect many times before. i even just added an hp 650 which has never been in our network before.

i tried adding the network manually, turned firewall off. none of these have worked. router settings remain the same as before, nothing has changed there.

I'd suggest accessing the router's wireless configuration and review settings because something is off.

Here's its manual.

If none of them even see the wifi, it is likely the wireless is disabled (turned off) so it is not broadcasting, or it is set not to broadcast the SSID in the wifi settings.

To err is human but to really screw things up, you need a computer!

Does the wireless button light change color when pressed?

EDIT: Top right of keyboard.

hi all

the problem was the channel that the router was broadcasting on. it was set to 13, i changed it to 11 and it worked. the devices do not detect networks broadcasting on channels above 11. i figured it out last night but since Trvlr mentioned it in his solution he gets the best answer selection.

thank you all

Hi - and thank you for feedback…

The channel issue was a long shot - as I have never come across it being an item to consider in general - when adding new kit to an existing network; unless I knew in advance that the router defaults either set to broadcast on other than (the usual) default channel 11?

What puzzles me though… is that the other kit which was working previously was able to connect via channel 13? And the hp 650 was also able to operate on channel 13 (as it appeared to work OK with router setting as was…)?

So if you have changed the router to broadcast on channel 11 have you also changed the other devices (previous kit) to operate/receive on channel 11 as well…

Otherwise how are they still connecting to the router? Do have vague memories of an auto mode for wifi but not sure if that's correct. Either the adapter could be set to scan for, and connect to, any active channel on a designated router SSID - regardless of what it was; or the adapter did it automatically/by default? And one could also manually assign the adapter to use a specific channel…

Which having said…when I check settings on my Macs various... I note they can handle a range of channels. I'm in UK at present - and as I didn't tell them to go to channel 11, when I set them up. I'm presuming they scan for and connect to the designated/selected SSID… via whichever channel they find the router is using? And when I'm in USA I don't change anything there for the Macbook I have and travel with (leaving it set to a GB location..) - and it connects automatically to my hosts wifi no problems; similarly the various airport (LAS etc.) wifi services too..

Have to admit my grey cells had me thinking that most (all?) wifi adapters worked up to and including channel 13. But when I check my elderly Acer Aspire 1692 I note it only goes up to 11…

The last post here (from a MAC forum):

http://apple.stackexchange.com/ques...

does give some insights/info regarding router settings - specifically channels used and where… Though it doesn't elaborate on how an adapter that only goes up to channel 11 might mange to find a router working in auto mode (on channel 13)? But it would appear that that poster had a similar experience to you re' router channels?

it seems that this particular device is not set to pick up channels above 11.

Thanks for popping back to let us know. Ch 13 is "relatively" new so this is one for us to bear in mind - nice one Khumo and trvlr.
