I have problems connecting with WiFI during some periods of day. I have wireless router in my house and three computers. One is connected with cable and other two have wireless network cards. Both computers with wireless cards experience same problems so I guess there is no problem with router or computers. Do you have any suggestion what the problem might be?
This issue is usually associated with areas with multiple wireless providers and networks. As you probably know, IP adress in network must be unique and when there are multiple networks IP conflict can happen. IP addresses conflict can make router unable to find computer on your network and to broadcast right signal. This issue can be usually solved with router reset and then rebooting computers in wireless network.
