The DHCP IP Address Range of the 655 is shown to be 192.168.0.100 to 192.168.0.199. Do I understand that it should be any number outside that range (obviously not 192.168.0.1) but do I need to take care that there is nothing else on the lan that has that number already?

Yes you should stay outside of the DHCP range, and you should avoid using an IP already in use by another static machine, but you should know what those IPs are since you would have had to manually set them.

You shouldn't, that's probably for mac spoofing when interfacing with a modem from your ISP, which is largely irrelevant at this point in time.

Great! Will save all that and see what happens when it goes back to where it will be used.

Will shout if additional questions arise. Otherwise thanks to all.

That didn't take long. I had selected WPA as the encryption.

Plugged the 624 in where it is wanted and attempted to log in with my Nexus 7, but a log-in screen unlike I have ever seen before came up. Here are the lines:

(Name of the router at the top), then:

EAP method PEAP
Phase 2 authentication None
CA certificate (unspecified)
Identity ____________________
Anonymous Identity ____________________
Password _________________

I have no idea what all of that means except the name and password. So I tried to login just entering the password that I set up for wifi, but got an "authentication problem" message.

First of all, I have not ever seen a login screen like that, and so assume that it had something to do with my settings in the 624 admin panel.

Any suggestions as to why the unusual screen and what I need to do to get logged in. Thanks.

Never seen something like that before. What if you use your router's login credentials (not wifi, but the admin/password that you need to access the setup page)?

Odyssey1942 02-17-2015 04:20 PM

Will try that next, but have already brought the 624 back to my computer to log into the admin panel to check my setting. However cannot find the admin panel at either 192.168.0.1 or at 192.168.0.99 (the fixed IP address that I gave it.

Flummmoxed!

Do I need to reset the router and start over?

michaelk 02-17-2015 04:27 PM

Are you plugged into a LAN port?

You can try using nmap to search for the router.
nmap -sP 192.168.0/24

You disabled the DHCP server. You're going to need to give your computer a static IP on the 192.168.0.x subnet and then connect to 192.168.0.99.

michaelk 02-17-2015 04:56 PM

Yep, I assume that it was already powered on...

Odyssey1942 02-17-2015 05:17 PM

the 624 is powered on and I am plugged into a lan port.

How do I "..give your(my) computer a static IP on the 192.168.0.x subnet and then connect to 192.168.0.99."? (In case it matters, this computer is a lubuntu OS portable without a wifi.)

Edit: would it be simpler just to reset the router?

michaelk 02-17-2015 06:33 PM

Look at the output of the console command ifconfig. If it does not show a valid IP address for eth0 then you need to manually configure it via

ifconfig eth0 192.168.0.200 netmask 255.255.255.0

Odyssey1942 02-17-2015 07:20 PM

I have to leave at 4am tomorrow morning, and so needing to move ahead, I had reset the router before michaelk's latest. Anyway now ifconfig shows an ip# at ethO as 192.168.0.100, but we had previously determined that was the computer not the router.

In the admin panel there are the following main categories:

DHCP
Wireless
WAN
LAN

I am certain that DHCP, at a minimum, needs to be configured. Here is what I did:
-disabled DHCP
-enabled static DHCP, gave it a name (which it forgot after saving), and set the IP to 192.168.0.99

For the moment do any of the others need to be configured?

In any case for security, I have attempted to set the wireless as follows:
-gave it a name
-I accepted the default channel 6
-set authentication to WPA

Below this were:
-Radius Server 1:
IP 0.0.0.0
Port 1812
Shared Secret (key? I failed to write anything after "Secret") and I left it blank
-Radius Server 2: (optional) [Does this mean that Server 1 is mandatory?
IP 0.0.0.0
Port 0
Shared Secret (key? I failed to write anything after "Secret") and I left it blank

I did not enter anything into either of these Radius Servers. Should I have?

So after all that, I get that same screen that I described earlier. I found this explanation:

http://www.cisco.com/c/en/us/td/docs...tionTypes.html

which seems to indicate that EAP is completely different from WPA. I have no idea why it is coming up since I am setting authentication to WPA.

Any ideas after all that (with apology for the length)?

Wait, what?

Static DHCP? A name? What exactly are you configuring here? Could you post a screenshot of the configuration page?

michaelk 02-17-2015 07:39 PM

No idea either but it looks like you are configuring the WAN or internet side vs the LAN side.

Odyssey1942 02-17-2015 07:58 PM

I reset the router again so that I could get back into the admin panel. I don't know how to put up a screen shot and in any case that portable is not online.

Here is what it says:

The top half of the DHCP page is labeled:
-DHCP Server
the bottom half of the page is labeled:
-Static DHCP
Immediately underneath is this sentence: "Static DHCP is used to allow DHCP server to assign same IP Address to specific MAC address"
Beneath that sentence is the stuff I previously described.

I hope this helps clarify any confusion.

This time, I did not enable WPAm, just left it open and I can connect to the internet just fine. So the issue has to do with the authentication settings

michaelk 02-17-2015 08:03 PM

You can ignore the static IP settings. That is for the DHCP server to assign the same IP address to the same client using its MAC.

All you need to do is disable the DHCP server and change the LAN IP address from 192.168.0.1 to 192.168.0.99.
