WRVS4400N Loses Protect Link Activation Code

Good Afternoon,

I have a Cisco WRVS4400N router with an active Protect Link license.  I recently began having an issue where internet access would cease to work.  Upon inspection of the router I noticed that the Protect Link feature was unavailable and that I had to enter the activation code again in order to get the feature to work.  Once Protect Link was enabled again, internet access would resume as normal.  The router has the latest firmware,  The 1 year license was purchashed in June and there had not been a problem until recently. I tried contacting Trend Micro for support but I was only pointed towards Cisco.  Any help or guidance would be greatly appreciated.

WRVS4400N Loses Protect Link Activation Code

Hi Martin, I am not sure why the Protectlink would prohibit the internet from working if the activation code was not present. If the IPS is disabled it shouldn't break the internet.

Anyway... one thing I had noticed on this router model over around the 10 years they've been around, they do have a tendancy to lose/drop settings due to power conditions. Have you had any environment changes lately? Storms knock down power? Change a power outlet or surgeprotector / UPS? If the device is regularly rebooting or regularly losing power, it comes as no surprise to me some settings are compromised and have to be reconfigured.
