I have a 7 64-Bit Desktop with 7GB RAM and a 3.06GHz Intel Core 2 Duo Processor. I initally connected my Desktop directly to my gateway/cable modem/router via ETHERNET cable. I noticed one day that I would loose my connection to the NETWORK and to the INTERNET randomly ALL DAY LONG. So, I checked all of the cable connections and made sure that the connections were TIGHT and SECURE. My NETWORK and INTERNET connections were still dropped constantly. I then went into the NETWORK ADAPTER settings and looked around. Everything seemed fine there. I then changed the Windows POWER setting to POWER SAVE or ENERGY SAVE mode. That did not help. I changed the setting back to RECOMMENDED MODE. That didn't help. I still would loose both connections all of the time. I thought that maybe my OS had become corrupted or something. So, I performed a SYSTEM RECOVERY from the Windows 7 Recovery Discs I made when I got the PC early this year. (that seemed to format both of my internal hard drives, so be careful). After getting everything up and running, I still would loose both the network and internet connections randomly. I then turned to my ISP. They replaced the cable mode/router/gateway, cables and splitters & checked the line signal. There was a line signal problem that made the modem/router/gateway drop PACKETS, but they have solved that problem. After all of that, I still loose connection all of the time via ETHERNET cable. I then thought of trying a USB WIRELESS ADAPTER that the cable company provided. I would loose connections with that as well. The cable company told me that there was something wrong with my computer on a few occasions. I doubt it. It's relatively brand new, plus it was working fine before I had them setup the cable line in my bedroom AND it was working fine at my previous address. Once they set up the cable line in my bedroom, that seems to be when started having issues with NETWORK and INTERNET connections. What else did I try? Umm...Oh, before I tried going wireless, I swapped ETHERNET cables for a BRAND NEW CABLE. Of course, that didn't solve my connection problems. I also went into the interface of the modem/router/gateway (I've had three different ones from three different manufacturers) and checked all of the settings. I have DHCP setup correctly. I do have QoS disabled (I don't know what it's for anyway). Last night I changed the DHCP LEASE to FOREVER. I thougt maybe that would solve the problem. That was last night, so I don't know for sure. With the latest router/modem/gateway that I have, the initial setting was for a week. I guess that is about how long it takes nowadays. That just might be the solution. We'll see. But, if anyone has any OTHER possible solutions such as, the wired and wireless adapter settings that I might need to change. I have a REALTEK PCIe GBE Family Controller version 7.23.623.2010 for the ETHERNET adapter. I have AUTO DISABLE GIGABIT and JUMBO FRAME disabled. I have INTERRUPT MODERATION, SHUTDOWN WAKE ON LAN, FLOW CONTROL, RECEIVE SIDE SCALING, WAKE ON MAGIC PACKET, WAKE ON PATTERN MATCH, and GREEN EHTERNET enabled. I have SPEED & DUPLEX set to auto negotiation. I have TCP CHECKSUM OFF-LOAD for IPv4 and IPv6 both set to Rx & Tx enabled. I have WOL & SHUTDOWN LINK SPEED set to 10 Mbps First. Also, under POWER MANAGEMENT for the ETHERNET ADAPTER, I have it set to that the PC can turn off the adapter to save power. I just placed a CHECK MARK there a second ago. Maybe I should turn it back off. Oh yeah, my cable internet speed is 25Mbps. Please respond with some very useful information and good advice. I appreciate it!
