ecs mcp61pm-hm usb wifi problems in Win 7

February 17, 2011 at 10:18:27
Specs: Windows 7, Athlon X2 5000+
I have a HP Pavilion 6130N with an Atheros USB wifi to connect to FIOS.

Since I upgraded to Windows 7, it will often drop the internet connection when it goes to sleep and not automatically restore it when it wakes up. Sometimes it won't restore it even when I try to get it to do so manually.

I did an upgrade to Windows 7 which did not yield some of the speed or stability benefits I expected. So I am thinking to wipe it clean and to a clean install, possibly with a Bios flash.

Any other suggestions?

HP Pavilion 6130N is apparently a desktop computer.

Did you install the main chipset drivers for your mboard after Windows 7's Setup was finished ?

If you didn't, you must install the main chipset drivers, otherwise Windows doesn't have the specific info about how the ACPI features - Standby, Hibernate, wake on...., and sometimes Restart - are supported by the mboard. (The main chipset "drivers" are actually mostly, or all, *.inf files - information files - that inform the operating system about the capabilities of the main chipset.)
......

If that doesn't help......

The USB network adapter may work fine after Restart if you plug it into a different USB port.

It may not work fine after Restart if it's plugged into a front case port, or into a port in a multiple port hub that's plugged into one port on the computer.

Thanks for the suggestion. Good thought, but I did reinstall the latest mainboard drivers from HP after the Win 7 upgrade. I followed the instructions for the Win 7 Upgrade Advisor to remove and reinstall several things.

You answered before I had finished editing response 1.There is more there now.

DO NOT flash your bios.
It makes NO SENSE AT ALL to flash your bios if your computer EVER worked fine before with the same bios version and CPU ! Bios versions are NOT operating system specific !

Not all mboards are compatible with Windows 7's ACPI support.
It's probably possible to install Windows 7 again without enabling it's ACPI support.

Wireless connections can be flakey for all sorts of reasons and your problems with that probably have nothing to do with you changing operating systems.

The most common reason for you losing a wireless connection is your signal between your wireless adapter and whatever it is connecting to such as a router is not strong enough.

The second most common reason, especially for a DSL or ADSL internet connection, is there is a problem with the reliability of the internet connection. In that case your wireless connection between your wireless adapter and whatever it is connecting to such as a router is fine - it's just the internet it isn't connecting to properly.
You often can't tell whether your connection to the internet from your standalone high speed modem, or your combo router / high speed modem, has a poor connection or no connection to the internet by looking at the leds on the front of it, if the led on the front of the device that indicates you have an internet connection was on previously - it's usually still on.
Try re-setting your internet connection.
If your standalone high speed modem, or your combo router / high speed modem, has a power switch, switch it off, switch it on - if it doesn't have a switch, unplug it's DC power cord at the device (pull on the plug, NOT the cord), plug it back in. WAIT a short time until the led on the front of the device that indicates you have an internet connection is working.
If your connection is DSL or ADSL, you MAY have to WAIT longer sometimes (I frequently do).

Thanks for the suggestions. I have the USB wifi device connected to a rear panel port. I tried other ports with similar results. I also tried a multi-port hub and the front panel connections with worse results.

Do you know if Win 7 ACPI is different from Vista ACPI? It worked better at reconnecting to the wifi network from suspend/sleep under Vista.

I'm getting a very good signal at the desktop. It is only ~25' from the router and on the same (2nd) floor, but layout is preventing me from running a cable. My laptop works fine from the same area as the desktop (and elsewhere throughout the house). I also had an old P4 machine running XP in the basement with a different USB wifi that got a good signal (but always had trouble restoring the connection after sleep - I figured it was just XP).

I tried the modem/router power off process with no improvement. It is running FIOS, a fiber optic cable system that has worked well otherwise.

Another possibly related factor. I often (not always) get a message that the USB wifi device could operate faster if connected to a USB 2.0 port instead of a USB 1.1 port. But it is connected to a USB 2.0 port.

The computer is about 3.5 yrs old now. I'm wondering a something like a capacitor on the motherboard might have gone.

"I have the USB wifi device connected to a rear panel port. I tried other ports with similar results. I also tried a multi-port hub and the front panel connections with worse results."

See this - the wiring between USB ports and mboard USB headers may not support USB 2.0 specs - devices plugged into a port in a USB hub that connects to only one port on the mboard often do not work correctly or are not detected correctly - etc. :

If you have a desktop computer, Note that I answered a Topic on this site where a guy had an external drive, which does require the full 500ma, connected to a port on the back of a desktop case - it would not work properly when a webcam was in the port next to it, but it worked fine when the webcam was unplugged. Ports on the back of a desktop case often have two ports connected to the same USB controller module that are ports one above the other - you could try connecting the USB wireless adapter to one of those and leaving the other un-used.

"I'm wondering a something like a capacitor on the motherboard might have gone."

If it has electrolytic capacitors, possibly, but many newer mboard models have all solid polymer capacitors.

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

This was the original bad capacitor problem - has some example pictures.

"Do you know if Win 7 ACPI is different from Vista ACPI?"

Windows 7 is primarily the same as Vista with SP2 updates integrated into it, with many of the things that annoyed people about Vista removed or made more user friendly - as far as I know the ACPI support of Windows 7 is the same as for Vista.

"I also had an old P4 machine running XP in the basement with a different USB wifi that got a good signal (but always had trouble restoring the connection after sleep - I figured it was just XP)."

Did you install the main chipset drivers ?

If the mboard is one older than when XP was first released, circa 2001, the ACPI support built into Windows XP may not be supported by the mboard.
XP can be installed from scratch with it's ACPI support disabled - Power Options settings usually still allow the mboard to shut off the monitor or hard drives in that case, moving a mouse or pressing a key wakes that up. You DO NOT need to use Standby or Hibernate modes with a desktop computer in any case - you can use Power Options settings instead.
