I have a TP-Link TL-R470T+ Load Balancing router setup at my home. Here is a link to the entire setup along with the routers connected etc. As can be seen from the diagram, I have three different ISPs (for extra redundancy) - all PPPoE connections.
The main reason I purchased the Load Balancer was that we wanted an uninterrupted connection. However, the connection often goes off for a few seconds to a couple of minutes, kicking users out of zoom call, logging them out of remote servers, etc. Currently, we've set it up in Load Balancing mode. Link backup hasn't been enabled because that causes only one ISP to be active at a given time. However, we also require the bandwidth, as at any point in time, there are approximately 20 devices connected.
The possible issues that I can think of are
- ISP failure - Very less probable as all thee ISPs will need to fail at the same time
- Load Balancer Configuration - Some setting in the Load Balancer Configuration I'm missing?
- Too many routers/Devices connected - The official documentation of the Load Balancer (Link here) says the device can support up to 10,000 connections, while we have only around 20-25 devices connected
- An issue with the router configuration? - All the routers are set up with the following configurations
- Mode - access point mode
- SSID - all have the same SSIDs and passwords
- Channel Interference - Shouldn't be an issue, as the routers are on different floors, and different ones have been configured for different channels.
Another thing I'd like to know is is it impractical to expect a seamless connection from a load-balancer? (E.g. No dropped frames in a video call even when one of the ISPs goes off). If so, is there a better alternative?
I've called the official technical support group multiple times. They suggest some tweaks like updating firmware, changing the DNS, etc, but most of them haven't produced any good results. Any help would be appreciated! Thanks in advance!
PS: I'd posted this Question on the Network Engineering Stack Exchange, but was redirected here!
Adding some of the suspicious entries of the system log
|Firewall||WARNING||Detected Ping of Death attack. Dropped x packets. (This occurs quite often)||This happens often, but is quite spaced out|
|PPPoE Client||WARNING||WAN2: PPPoE sending PADI timeout.||Happens once in a while|
|Firewall||NOTICE||Detected ARP Conflict. Dropped x packets||This occurs rarely, but when it occurs, there are multiple similar logs, in a small time interval, leading to loss of many packets|
|Firewall||Warning||Detected suspected ARP attack packets. Be careful||Don't know what to make of this. Comes once in a while|
Hope this can throw some additional light!
