Hello, I recently bought a new computer and am having great difficulty with the wireless connection. Here are the facts... - My old computer started having problems with being dropped from the internet, which was a fault of the modem - we had a Linksys router which never required resetting or dropped the connection - The server company replaced their old modem with a Speedstream 6520 modem/router - The problem wasn't completely solved but I could use the internet...it only disconnected perhaps once or twice a day and I could easily reconnect - the old computer bit the dust and I had to purchase a new one...Samsung np300v5a - I can sometimes get a connection on the wireless but it is weak, very short-lived (sometimes no more than a few seconds), and sometimes it takes multiple tries to get a connection, which sometimes doesn't happen at all - it will say that it is connected, or has limited access, but there will be no response on the internet and I'll have to disconnect and attempt to reconnect. - restarting the computer doesn't solve it often - using the safe mode with networking works much, much better - the router is perhaps 80 feet away - just got a message from AVG saying IE is using too much memory, but I only have 3 simple tabs open Here are the things I have tried, with all the research I've done: - ran Microsoft Essentials, AVG scan, AVG PC Tuneup Spybot, Malware Bytes to clean the machine - reset TCP/IP with online "fix it" - reset winsock - did ip/release and /renew manually - turned off firewall but turned it back on when there was no change - tried different channel - tried static IP - downloaded latest network driver - firmware and drivers are all seemingly up to date - turned off IPv6 - made sure proxy servers are not enabled - made sure DHCP is enabled - just did netsh int ip reset reset.log manually - have "Roaming Aggressiveness" and "Transmit Power" at highest levels. - "Allow this computer to turn off this device to save power" is unchecked No change. The other computer in the house seems to have no problem, but it is less than 2 feet from the Speedstream, and the user rarely ever uses it enough to even notice. She did, however, get a message about another computer in the house using the same IP address. I am using Windows 7 and IE9. I have downloaded Hijack This in case it is needed. Thank you for your time and assistance.
