Why does my laptop not connect at home but connects at work

Specs: Windows 7
I have a laptop that does not connect but other devices have no issue. I have reset my wireless router once and it worked for a one day and then stopped.

The laptop sees the wireless network from available networks

Some more information would be useful.

Make and model of laptop. Make(s) and model(s) of routers involved.

How do you connect to the network at work; and also at home?

Is your office connection via a Domain, a simple peer-to-peer network/work group?

Also, is this a work laptop that's been setup at work by the IT people (person) there?

It is strange that the laptop stopped when a family member stayed for 2 days and connected to the wireless network. So I thought that there were too many wireless devices connected. I recently needed to move 2 desktops to a room and make them wireless. So there is 11 devices connected including 5 phones, 4 laptops, 2 desktops

Netgear 150

I connect wirelessly everywhere. I rarely connect with a wired connection.

While there may be a limit on the number os client connections to a given (wifi) router... It's generally a lot more than 11.

This is the manual for your router; page 32 is the start of wifi setup.

Is there "any" form of access control invoked (in use) for your wifi access? This can be as basic as the usual access key (and there is a default one set, and which of course one can change); and there are assorted flavours/varieties for this. There is also a system called Media Access Control (MAC) which allows three options. Allow anyone/everyone to access; allow only those in the list you create - thus disallowing access to anyone not on that list; disallow those in that list - thus allowing access to anyone not on it.

Similarly your work environment may (one would hope they do) operate/apply some form of serious access control... Preferably the latter - MAC.

So have a look-see at your home wifi setup, and see what is configured there. It may well be that if your home system uses one of the MAC options the laptop in question is not on the allow list (and previously it was) - whichever list is in use...?

My question is that why for 3 years was it okay and then all of a sudden it fell off? When I looked at the MAC addresses I did not see any computers. I thought that was strange. I tried to refresh it but did not get a list. Maybe I was looking at something different. I will look tonight when I get home. I will check for the options also.

Can understand the puzzlement... The "connection" for me is the family member's visit for a few days... Possibly something was tweaked then on the router?

I'm presuming that you have re-entered the wifi access info on the laptop in question -having first "forgotten"/deleted any prior entries.

Also check that it is using the correct wifi channel; that whatever the router is broadcasting on... the laptop is set (tuned as it were) to that channel.

That is a good question. I reset the router to manufacturer settings to get a new start. and the laptop connected for one day and then stopped. This was after the family member left. I will check the channel tonight on both the laptop and router

This, to me, indicates a problem with the laptop in question.

I would suggest you start by ensuring you have the most up-to-date drivers for the wireless interface installed on the laptop. If a driver update doesn't fix the issue, you may have to un/reinstall the interface itself on the laptop (again, ensuring most recent driver).

I am back. I reset the router to manufacturer settings and it worked for a month. It has now come back and I am unable to connect on the laptop again. the other day nothing would connect wirelessly and I restarted it and it everything connected but I did not check my laptop. Last night I tried and it would not connect again.
I just found out that my son had connected a router to his line in his room so his wife could be connected with a hard wire. I wondered why they never complained about connection issues on her laptop.

So does this mean there are now "two" routers across the one incoming dsl line/service? And is the second one also operating in wifi mode as well?

And again - does "your" laptop connect via cat-5/ethernet OK - or not - to "your" router?

I will check all this out tonight My son said that the second router has been hooked up for awhile now. How would I know if the second router is running in wifi mode?

It (your son's router) would be by default broadcasting its SSID and that would thus be shown in the list of available wifi access points; and also if you were to access that router's management area and go to wifi settings - then you would see if it's been enabled (or not)?

There is of course the possibility that wifi is enabled, but that the SSIID (by default "visible") has been "hidden"...; which would mean of course it wouldn't show in the list of available wifi access points in the vicinity.

You might also check to see if the other router is using the same ip address (supplied by your isp) as "yours". If so... I suspect that may be the actual problem for you. As best I understand it - one cannot have two routers on (sharing directly) the same/one dsl service... One can have only one router one any one given dsl service.. If you need two routers then they either are set to share it - i.e. one (the "primary/master - my descriptor) is "feeding" the other - as in extender/extended roles...

If you disable the "other" router and re-enable your, possibly even initially a reset etc. too, that would be one way to verify if it is the "other" router that is the problem?
