Have an unusual situation with the wife's laptop and looking for any and all ideas or suggestions.
Laptop:
Acer 4530
AMD Turion dual-core @ 2GHz
3GB DDR2 667MHz
NVIDIA nForce MCP77MH chipset
NVIDIA GeForce 9100M integrated video
Atheros AR5B91 802.11b/g/n wireless nic
Windows 7 Pro 32bit
Steps taken to correct:
updated all drivers
high gain antenna on wireless router
New wireless router (from Linksys WRT54GL w/tomato to Netgear WNDR3700-100NAS w/DD-WRT)
g signal only
n signal only
USB wireless NIC
Situation:
Onboard Atheros wireless NIC getting poor signal, after taking some steps to mitigate the issue and increase signal reception, purchased and installed a USB wireless NIC, USB NIC solved reception issues but caused the screen to flicker to the point of being unusable, screen stops flickering as soon as I disconnect the USB NIC.
Also worth noting that I have no screen flicker or reception issues with either g or n when connecting my Dell D620 with either the onboard wireless of USB NIC. Get full signal with both onboard and USB wireless throughout the entire house (3 stories) a well as in the front and back yard (up to 120 feet straight line from router) without issue; so the issue is specific to the Acer 4530.
Any ideas as to why the USB NIC would cause the Acer 4530 screen to flicker? I understand that screen flicker is indicative of a bad screen or bad cable, but as noted the screen only flickers when the USB NIC is connected.
Suggestions and input are welcome, thanks!
