every once in a while (about once a day) my router's lights will just all freeze and I lose internet connection. I power it off and turn it back on and I usually get conenction again only for it to happen again maybe in a day or two...Sometimes when i power it on and off the lights come back on as frozen again and I have to keep switching it on and off until it comes back on properly. I have no idea why this happens. I got it in Sept last year and this problem only started happening in the last month or so. I am using the latest drivers for it (Which are about a year old).
Anyone know why this is happening?
Its a D-Link 784 router. Supposed to be a good one but I'm disappointed with it.
