When changing wifi networks, TC won't connect anymore. . . ? [solved]

[ghosts]

Not really sure how to describe it, so I'm hoping someone can help me.

Before, there hadn't been any problems with TC and my wifi card (realtek 8188ce). It was able to detect and connect to the network easily.

However, a new network has been put in place, which will soon replace the old one. At first TC was able to connect to this one maybe once in several tries--which is problematic already. Now it refuses to connect at all. It's always the same, it always ends with "no lease, failing".

When I try to connect to the old one, it does so without fuss. But that one is going to be disconnected soon, so I need TC to work with the new connection.

I'm not sure what the problem is, so I don't know what information is necessary  I'm hoping someone can help me out, as before the new wifi network TC has been pretty much perfect and I'd hate to replace it

I've read a few of the wifi-related threads here but couldn't seem to find one that solved mine. Hope this isn't a redundant thread though, but I've spent quite a bit of time trying to figure this out U^_^

I would check encryption type and othe settings of the new AP you can't conenct to. Use

iwlist scan

command and share result.

According to my windows laptop:
The old network's security type and encryption type is WPA2-Personal and AES respectively
For the new one, it's WPA-Personal and AES.

However, it seems to be different in Linux--

Running "iwlist scan" had very long results as there are several networks. I typed out the parts that seem to be related to encryption here (although I could download lxterminal or something and copy-paste if the entire output is needed)

The old network:
IE: WPA Version 1
     Group Cipher : TKIP
     Pairwise Cipher (2) : CCMP TKIP
     Authentication Suites (1) : PSK

The newer network shows exactly the same, actually.

Except for the numerous alphanumeric strings following  the repeated "IE: Unknown"s (and it gets pretty long), there doesn't seem to be a lot of difference between the two.

Hi ghosts

(although I could download lxterminal or something and copy-paste if the entire output is needed)

Or, you could:

Code: [Select]

iwlist scan >> iwlist.txtand attach the file to your next post. If you prefer copy/paste, you could then:

Code: [Select]

editor iwlist.txt

Uhmm, what's wrong with copying from aterm?? (Or am I missing something here?)
If you don't use X, the gpm extension would allow you to copy and paste.

[ghosts]

in other terminals, I'm just just to using right-click to copy and paste text; I couldn't do that with the default terminal so I assumed I couldn't =)

What's the point of simplicity if it's possible to complicate things?

http://tinycorelinux.net/faq.html#c_p

old habits die hard  I didn't even know what a Linux distribution was maybe seven or eight months ago ^_^ In Windows, right-click is constant. . . kind of hard to get out of that mindset =)))

Anyway, thanks, I probably passed over that part when I read the FAQ =)

Hi ghosts

According to my windows laptop:

However, it seems to be different in Linux--

You scan shows:

Code: [Select]

                    IE: IEEE 802.11i/WPA2 Version 1
                        Group Cipher : TKIP
                        Pairwise Ciphers (2) : CCMP TKIP
                        Authentication Suites (1) : PSKis missing from the new network.

[ghosts]

?
I'm afraid I don't really understand. What can I do about it?

[Rich]

Hi ghosts
I was only pointing out that the Linux scan agrees with what Windows reported, the new network does not
suppport WPA2.

[ghosts]

I see. So far, connection to the new network will fail 9/10 times. The "sending discovery. . ." line repeats itself a few times before failing to connect.

It's not something that has happened with the old network though

Is there anything I can change to be able to connect to the new network consistently?

Hi ghosts

thank you very much
I can connect to it now~
the wiki is great
