Our company is currently providing cable internet. Our set up is , we have 2 ISP, connected to CISCO 1841, then to a cmts (cable modem termination system). Unfortunately, 2 isp's cant go live simultaneously and we have been experiencing latency consistently. Please help me know how can we solve this problem. How can we make 2 isp work , or do we need to upgrade the router? does the ios support 2 isp? i would appreciate if you can provide me solutions to this. thank you
