Intermittent Unidentified Network and No Internet Access

[machm1217]

When trying to connect to my home network, it is successfully connecting; but its registering as an unidentified network with no internet access, it identifies the network but still has no internet access, or it doesn't identify the network and i have access to the internet. It likes to switch back and forth between these periodically. I have already tried updating my drivers, resetting my router, rebooting my computer, resetting my wireless adapter, resetting my tcp/ip, turning off/on my firewall. Is there anything else anyone can think of to fix this?

 

I'm running windows 7 with windows security essentials, im using the Rosewill RNX-N180PCe wifi card with the RTL8191SE Wireless LAN driver. If anyone needs anymore information please ask, any help is appreciated.

Is your router or wifi card new?  

[ShearMe]

Fyi, this is my computer Mr. MachM is borrowing.

 

 

Is your router or wifi card new?  

 

No, it's about a year old. We recently re-installed windows, hence the sudden issues.

[machm1217]

Yeah its not very old, I did re-install windows a couple of weeks ago. But this started occuring just a couple of days ago, so I figured that the windows installation had nothing to do with the problem, but you never know when it comes to these things. I have other wi-fi cards lying around though so I might try one of those out to see if its a problem with the card.

Try static IP address.

 

Sometimes (depending on router), if you set incorrect IP address, Local Area Networking will work fine, but Internet access will not. Here is example for two common addresses:

 

If router address is 192.168.0.1 (TCP/IPv4), then try as follows (assuming that modem is connected to the router input):

 

IP: 192.168.0.10 (any number with numbers 3 or above and bellow 100 - 99)

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.0.1

Preferred DNS Server: 192.168.0.1

 

If router address is 192.168.1.1 , same as above, but 1 instead of 0.

 

192.168.1.10

255.255.255.0

192.168.1.1

192.168.1.1

 

Just make sure than none of your PC's on network go above 100 (in some cases) for IP address (last number), especially if is with two or more routers or switches etc.

 

If there are two routers, you need to type IP address, gateway and DNS that goes for router where modem is. For example: One router have address of 192.168.0.1, and that router have modem connected to it. 2nd router have address of 192.168.1.1 and no internet connection, but it is connected with other router trough switch or directly.

 

In this case, no matter on which router your PC is connected, you need to type address of the first one for every PC in order to ahve both LAN and internet connectivity, that means 192.168.0.x (and 192.168.0.1 for gateway and DNS).

 

Hope it will be helpful and not too confusing.

quick question, i check the ipv4 and its ending up as .101, you said that it shouldn't be in the 100's right? what do

 

EDIT: I tried the static IP trick and it still didnt work for me. Either it identified the network with no internet access, or it didnt identify the network but "with internet access" (still couldn't connect to the internet anyway)

[machm1217]

So i put in a Linksys USB wireless adapter and it works fine. I'm going to chalk this up to a corrupted wi-fi card.

 

 

Fyi, this is my computer Mr. MachM is borrowing.

 

Shearme you can have it back :D

It shouldn't go voer 100 in those type of connections i did described, but in your case, it should not matter, for some reason, you don't have internet access, and it is probably broken wi-fi card or drivers.

 

I'm sorry, i did overlook that it is wi-fi. Those are unreliable connections, regardless what you do at the end (fix the problem), if is possible, use wired connection.

[ShearMe]

I aint want no broken pc components - I'd be mad at you if it wasn't a $20 junk card I don't need.

Mark the thread solved if you're not gonna try to fix it.

Hide them :P. Well, i will not spam this thread with off topic, hope someone who knows wi-fi a bit better can help actually

192.168.1.1

 

Just make sure than none of your PC's on network go above 100 (in some cases) for IP address (last number), especially if is with two or more routers or switches etc.

 

I'm.. just... wha?!?!

 

I'm quite confused about what you're saying.

Ah, what? the IP addresses in a class 3 (or /24 in CIDR) should have IPs addressable from .2  all the way to .254

 

 

(any number with numbers 3 or above and bellow 100 - 99)

Again, addressable IPs should be .2-.254

 

Sometimes (depending on router), if you set incorrect IP address, Local Area Networking will work fine, but Internet access will not. Here is example for two common addresses:

The only two things that you'll have issues with is if you set a non existing DNS as your DNS, or if you miss typed your gateway IP (then you wouldn't have an LAN connection). If you messed up and assigned yourself to a whole different subnet, then you have internet, but no LAN.

 

OP: Right click the little network icon on the taskbar, then click "Troubleshoot Problem". Let's see what that says

I don't have any problem, OP have problems with WI-FI connection ;).

 

There are reserved IP addresses, and usually 2 is (depending from configuration), so 3 is and above are available. In case you go by the rule PC-router-switch-router-modem, again, depending from configuration, IP above 99 just don't work for LAN (not internet, my bad).

 

Networking can be full of issues, and as you can see, that was part of the issue, luckily, i don't connect over 96 PC's in that configuration.

If you put your modem into bridge mode, then it will send the packets straight to the router. IPs above 99 DO work for LAN. again, IPs in the range .1 to .254 are addressable (.0 is the network ID and .255 is the broadcast IP), but EVERYTHING else in that range is assignable. 

 

PC-router-switch-router-modem

Why do you have this??!?!? This is a horrible setup.

 

Modem-Router-PC (if you're at home). 

 

Modem-switch-AP (buisness)

Where did i say that it should not work? Seriously, we are off topic, and we are not very helpful to the OP with this.

 

You can theorize all day long, I'm telling you, in that specific configuration, it DO NOT WORK. It is large network, and it is not in home only,a ctualy there are more switches and routers, I've just gave one example where IP above 99 for whatever reason do not work. One (well, even 5, let alone 1) switch can't do the job for this scenario, that is the reason, no one wants cable mess... and non efficient cable usage.

 

That being said, it is possible that same problem can be in other scenarios, therefore, that's why i even mentioned that, but, i was wrong since i did overlook OP post where he said it is WI-FI connection.

 IP above 99 just don't work for LAN

Right there.

What is your networking background?

Also, I'm waiting for the op to reply to what I asked him to do ;)

[leipero]

Ok, don't do those tricks putting something out of context :P. We really don't help to OP with those smart*ss talk . Here is what i said:

 

"There are reserved IP addresses, and usually 2 is (depending from configuration), so 3 is and above are available. In case you go by the rule PC-router-switch-router-modem, again, depending from configuration, IP above 99 just don't work for LAN

"

 

And to the OP, i said: "IP: 192.168.0.10 (any number with numbers 3 or above and bellow 100 - 99)", just to rule out that possibility, no other reason, anyways, he would probably use Ip bellow 100, so no big deal out of it ;).

 

Now let's stop spamming this thread with non relevant things,a s i said, for some reason, in this specific configuration, it DO NOT work, now, is it possible to work on another? Yes (probably). Is it possible for another to have exact same problem? Yes.

 

But all that is irrelevant to the OP, because i didn't read well what he wrote.

 

EDIT: Here is the reason why \i avoid this off topic discussion.(and i like to chat, don't get me wrong). Imagine, few days from now (or one year, or whatever), someone google search model of the OP device and same exact problem, now, he reads, and he have to read all non relevant things we wrote (ok i started with bad read of OP) to find out solution maybe on few pages latter. It is very irritating thing to go trough (i know because i was in that situation few times). So, i would love to chat, but, it will harm this thread. Althought, that is why best answer is there :P

[machm1217]

I'm pretty sure that the adapter was broken, I went and changed the properties off the ipv4 (on my pc) to the configuration that my laptop automatically registered when connecting to the network. I then disconnected the laptop form the network, shut it off for an extra measure, and enabled my pc wireless adapter. It didn't work either.

 

Its as good as removed from the computer blade of grass, im sorry i can't answer your question but thank you for the input. Everytime I tried troubleshooting anything I got a gateway problem or point of access problem, if that helps you.

funny story, my dad suggested that i just run an ethernet cable

That'd not last longer than as soon as your step mother got home. :P

Guys, don't worry about this thread unless you have some specific insight - we'll just toss the cheapo wifi card out the window.

So you're done with it and will just get a new one? Cause I have a few more things that may help, or at least can give me some more info on figuring out the issue.

But if you don't care, and you're going to buy a new one, cheers!

[machm1217]

if you have a few more things to help people on this forum with this problem then go ahead and post them, i already told you what i was given when i used troubleshoot

Then post them instead of asking if you should post them...

Hey, if he doesn't care, and he's done, why would I waste time typing it out?

 

Here's the short version:

• Open a command prompt and type in "ipconfig /all"
• screen cap and post the result
• type cls and press enter
• type "ping www.google.com"
• screen cap and post the result

That's to see what you're getting, and I'd go from there.

[Jesus]

OP: what is your network topology? Include model numbers as well please.

If nothing is working, try adding your computer to a DMZ on your wireless router.
