What is the parkervision wr1500 defaul password?

You won't get internet connection that way because there is no connection between the first parkervision and the 2nd one.
Best way is use only one parkervision router. Connect WAN port to modem for internet, 1st lan port connect to your pc and 2nd lan port connect to 2nd pc in other room. 2nd way is, use only one parkervision. Connect WAN port to modem for internet, 1st lan port connect to your pc, setup wireless SSID and connect your 2nd pc to this router for internet wirelessly. Assuming your 2nd pc has wireless capability.

Connect your router to computer with ethernet cable then you can access it with following default link. http://192.168.1.1 or http://192.168.0.1 or http://192.168.15.1 or http://192.168.2.1 If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it. Then it ask for user name and password. Type user as "admin" and password as "admin" or "password" or blank. Then you can see configuration page of router. If you are still not able to access router with above ip then you need to RESET it for that press RESET button for 10 seconds it is in back side of router then all settings defaults..Then you can access it with above method. . Then click on wireless->wireless security->WEP security there is code password note down it or enter new password then save setting s and restart router. then you can connect wireless with new password. Let me know if you need further assistance. Thanks for using FixYa.

You need to log into the wireless router either by a computer that successfully connects wirelessly or by physically connecting with an ethernet cable. Once connected, log into the router by open a web browser (Internet Explorer, Mozilla Firefox, Google Chrome, Apple Safari), and typing the router's address (usually 192.168.1.1 or 192.168.0.1) into the Address (or URL) line. The default usernameand password is usually "admin" & "admin" or "admin" & "password". Once successfully logged in, look for a tab or link that says "Wireless" or "Security". You'll be able to change whether security is enabled or disabled, and the password associated with it. Your security options are WEP or WPA (or WPA-PSK). WPA-PSK is the most secure, but WEP is also an acceptable choice. Select the security option of your choice and either enter text into the passphrase generator or choose your own password and type it into one of the security key text fields. If you use a password that is not a plain english combination of letters and numbers, be sure to write it down so that you can enter it as needed on other wireless devices that need to access your router (ie-pda phones, game consoles, laptops, desktops, etc). Be sure to save changes so that the security settings and password is saved.
Let me know how you make out.

You want to secure the wireless network.
Is there any computer connected to the router with the Ethernet cable?
If not then you will need to connect the computer to the router with the cable.
Check the IP address on the computer. Open the router set up page.
Once you open the set up page, you will find the option to make it secured

HI,

Please click on the below link to download manual for your model:

http://www.retrevo.com/s/ParkerVision-WR1500-Wireless-Routers-review-manual/id/8352dj893/t/1-2/

The power supply on my ParkerVision WR1500 router is 12 vdc, 1.2a, center pin positive. http://straylightsoftware.com/downloads/parker2.html

A complete download package (driver, GUI and manuals) can be downloaded at http://straylightsoftware.com/downloads/parker.html

from the original docs:

Reset Button
The WR1500 Wireless Router reset button is built into the rear panel. Use this button to restore the factory default password to 1234; IP address to 192.168.1.1, subnet mask to 255.255.255.0 and DHCP sever enabled with a pool of 8 IP addresses starting at 192.168.1.33.

note my unit resets to ip 192.168.150.1

it seems that the wr1500 doesn't have a DMZ feature. im not sure if it has a latest firmware that will provide DMZ but what you can do is use the port forwarding feature. you just need to know the ports of the applications that you want to pass the router's firewall

hope this'll help you and just ask me if you have other concern

ciao!
