Wireless Router Gateway Installation Guide10

Troubleshooting
Table 2: Troubleshooting information
Problem Resolution
When you launch a web
browser, it does not direct you
to the WRG login page.
Reason
Device operation varies based on the device and internet browser that you use. For
example, some devices cache browser information and do not automatically redirect you to
the WRG login page when you launch the browser.
Solution
Direct your browser to http://www.wrggateway.com or the unique Device URL supplied in
the Wireless Router Gateway WRG1830 Quick Start Guide (Part No. 24-11460-00026).
Note: You must be physically connected to the same Ethernet subnet to use the
Device URL.
When you upgrade a wireless
controller or HVAC device that
an WRG is monitoring, the
WRG does not display active or
current data for that device.
Solution
Perform a Rediscover Devices from the Device List view on the WRG.
When you install the SSL
certificate on your device, it
asks you to re-install it.
Solution
1. Verify that the time on your client device is correct. If the device time is not current,
for example, after a hard reset, close the browser, set the time, and then try to install the
certificate.
2. Check your web browser settings and verify that cookies are enabled.
When you install the SSL key or
certificate, the message Error
Saving SSL Settings appears.
Reason
When an SSL key or certificate is corrupted, the SSL page detects it and alerts you to the
corrupted key or certificate. However, if the corruption is minor, for example, if you copy
an extra space while you install the certificate, or you miss a character, the UI does not
detect the problem and saves the corrupted key or certificate. The server detects the error
and returns the Error Saving SSL Settings message. This correctly prevents the bad key or
certificate from being used, but it does not inform you about the source of the problem.
Solution
Reinstall the SSL key or certificate as described in the applicable WRG1830/ZFR183x Pro
Series Technical Bulletin.
