Windows 7: Acer Aspire 5749 Series WiFi Connection Dropping

Windows 7: Acer Aspire 5749 Series WiFi Connection Dropping

Hello,

I have essentially the same problem as Jesse where it is not a problem with our wifi network because all other devices are working properly and have no problem using our wifi.

The difference between my problem and Jesse's is that I went to Device Manager and clicked on the Network adapters link and it has a different set of drivers:

It has 3 listed:
Broadcom 802.11n Network Adapter
Broadcom NetLink (TM) Gigabit Ethernet
Microsoft Virtual WiFi Miniport Adapter

I went to Acer, and just to make sure, I used their Hardware Vendor Detection tool, and it listed that this laptop uses Wireless Lan: Broadcom. So I downloaded the Broadcom driver that Acer has on their support site. This did not solve the problem. Actually, although the laptop would connect and then drop the connection now it isn't even connecting.

I went to the Broadcom website and they have a slightly more recent driver (still 2011) but it asks me what technology I have and I just don't know which to pick for what we have. We use wifi through Time Warner Cable, so is that Cable + Set Top Box?

Maxie or anyone else have a suggestion?

I currently am using the laptop wired directly to the internet so I can connect just not through wifi.

Thank you in advance for any suggestions.

Hi Maxie,

Thank you for responding to my call for help!

My Acer Aspire has Windows 7 Home Premium and yes it has all the most recent updates up to 4 pm today.

I don't know how to update the modem / router firmware, but our family has many devices, including 2 other laptops (1 windows and 1 mac) and various tablets and a mac desktop and none of them are having any trouble whatsoever with their wifi connection. Which makes me think it is a problem with this particular laptop. I have not taken it to connect anywhere else, so I don't know whether it would work with wifi networks somewhere else.

If you could tell me how to update the modem/router I will do that next.

Thank you in advance for your time and patience with me as I am not very well versed in these issues.

It would seem you are correct seeing as you have the issue with just this Laptop ... There is no real point in updating the Modem / Router ... So the next step would be to update the Driver for the Network Adapter ...


I will search for a Driver in the morning and Post a Link for it ...


I have read a few Posts concerning this Network Adapter which quite a lot of people have had problems with it in the past ...


But we shall see how things go before we consider if that might be the problem ...

Are you still having problems connecting to the Net ? If so have you tried to roll back the Driver ? ....


At the present time I have managed to get a loan as the same Model as you have ... Though so far have not experienced any problems with the Adapter ... Still I am testing some Drivers to see if that makes any difference ...


I did Install the Driver from the Acer Website that proved not to work so well the Windows Driver seems to work much better ...


Have noticed though that it does not seem to have a constant Signal seems to drop a bit ...

Hi Maxie,

Sorry I got so busy in the pm that I didn't check for your reply.

That's great that you borrowed the same type of laptop.

Still can't connect to wifi. I have also tried different browsers just to make sure.

Does roll back the driver mean to go back to a prior version of the driver?

If that is it, could you point me to where I would find prior versions?

Also, maybe I should try the Windows driver you mentioned, where is that available?

Thank you for helping me with this.

The "rollback driver" button is off, so no option to rollback.

I clicked on "update driver" to see what it would do, and that came up that the driver is up to date.
