I can't tell if this is the usual hidden SSID or paper thin WEP security in use.
Tell a little more.
I have a used Dell Latitude D610 that I just bought on Friday from Discount Electronics. The wireless is card is Dell Wireless 1370 WLAN Mini-PCI C. It keeps on dropping it's signal every 5mins and goes back on for another. When the signal is on, it says it still authenticating. I took back to the store and it worked fine too. The main modem is a Netgear modem from Time Warner. My mum and my sister's laptop work fine. What can I do to fix it?
