If the cable modem lights are doing that, consider reducing the number of devices on your cable network (yes, it is a network.)
The cable company usually sets you up and measures signal power at the cable modem but time and time again I see folk add more TVs or other things but not have the cable co re-test this. And no, I don't write about this as a DIY method.
One last idea? Be sure the cable modem is cool. That is, don't stack a router or phonebook on top of it.
I am having a problem with my modem and would like an advice, if anyone has any.
First of all, this is how my connection looks like:
PC & Xbox 360 -> Router (Linksys WRT54GL with DD-WRT firmware) -> Modem (Arris TM602B)
Everything is working just fine, except for every now and then (sometimes a few times per day), when my modem decides to "stop working" for a second or two. I do not know if it is exactly the modem, but i guess that it is.
What happens, is that for a second or two, all the lights on modem stop blinking or turns off, except "Power", "DS" and "US". Those lights stays turned on. After a second or two, all the lights continues working normally.
It would not even be that big of an issue, as i would not mind if my internet radio has stopped working for a second or if i had to wait a second before continuing with browsing the web, but it becomes an annoying issue, while i am playing video games on Xbox Live. This is what causes me to disconnect from an online game, even though, everything works normally after - until it happens again.
Is there anything that i could do, to fix this issue?
If i need to provide anymore details, feel free to ask!
Kind Regards, Zerothe!
