I have an SR520 installed (along with several other Cisco products) and use the ADSL version. This has been a rock solid product, working without fail for over 3 years. I have periodically updated as new IOS releases have come out, and I wanted to update to the latest release that addressed the known security flaws in the product.
However, now that this is End-of-Sale it seems I have no way to do so, and Cisco requires a service contract to download the software. I don't need the added features, I just want the patch for the security flaws in the product.
Can someone point me to a potential resource?
