[Cable HSI] Repeater continually disconnects I was hoping someone might have some insight, or experienced a similar problem. I just bought a new Asus RT-N12 router to use as a repeater when Mediacom installed a new router/modem gateway and the old one seemed to stop working. This router has a switch to set for repeater. Now I am experiencing the same issue with the new one. I can connect to my network fine, but it disconnects after 20 minutes or so. Resetting the cable/router does nothing. I have to reset the Asus and set up the connection again. One thing I noticed, and I have no idea if this is part of the problem, is that my modem/router has an ip address of 192.168.100.1 and the Asus is assigned an ip of 192.168.0.18. But if that were the issue, wouldn't the Asus fail to connect to the gateway at all?
Asus is no help at all. The tech is scratching his head. He claims it must be due to the modem/router settings as it has happeend with both Asus repeaters. I think he may be right.
Usually the cable modem is known as 22.214.171.124 on the inside -- that is not the issue.
It seems to me that your cable modem/gateway is not talking cleanly to your separate repeater, such as due to wireless interference. What happens if you connect by a laptop back to the Mediacom gateway from the exact same spot, with your repeater turned off? Same issues or okay? Why are you even needing a repeater in the first place - is the house too big or other reasons?
Yes, we need a repeater for the Smart TV to get a strong enough wireless signal. Once the repeater disconnects, we aren't able to connect back to the gateway until we physically go downstairs and stand next to the gateway. Then the laptop reconnects and stays connected (most of the time) even when we go back upstairs. I'm not sure what this means, do you? BTW, the same issue happened regardless of repeater location. I tried setting it up downstairs below the Smart TV, and upstairs in the same room as the TV. Both places disconnects happen.
I am not familiar enough with ASUS equipment to help you directly, and apparently there aren't other experts on this forum who are either, as no one has responded.
However, if your need for a wireless repeater is primarily to feed just a particular TV, then I would suggest a different solution: I believe you might be better served by configuring a "client bridge" instead of a repeater. That is setting up the ASUS as a specific reception point of your gateway to connect a remote device, but not repeating the signal. This presumes that you can then connect your smart TV into the ASUS by wired connection. DD-WRT is a popular software to use to configure the firmware to then function as a client bridge. I've done similar with Linksys equipment, plus putting "reflectors" on the antenna of the Linksys client bridge to narrow its reception in pointing just to the gateway. This worked between two adjacent buildings.
While checking that idea, I ran across this discussion on the DD-WRT website that talks about better performance and connectivity with your ASUS by reducing the power levels of the devices and/or reducing the bandwidths of the signals. I don't know if your standard ASUS configuration allows you to adjust those. Here the link to that discussion:
