Hello everyone,

I purchased an Aspire R7 a couple months ago and was terribly dissappointed with the wifi connectivity. I see a lot of users have had this issue as well. Well today I fixed the problem and it is very simple.

1. Navigate to your Device Manager

2. Click on "Network adapters"

3. Double-click on "Braodcom 802.11n Network Adapter"

     #A new window should open.

4. In the new window click the "Advanced" tab

     #I changed two values

5. Navigate to "IBSS Mode" change value from 802.11a/b/g Auto to 802.11a/b/g Performance

6. Navigate down to the last property ("XPress (TM) Technology") change value from Disabled to Enabled.

MY SPEED WENT FROM .75MBPS TO 20.14MBPS ON THE OTHER SIDE OF MY HOUSE. 

Please comment and let me know if this works for your R7 or any other Acer laptop.

If this does not work also try setting "IBSS Mode" to 802.11a/b/g Auto

i tried this and i did see a incress on the speed a bit but when i watch netflix or play my music on my google play music it play for a bit then gets all crappy again, it work fine when im close to my home router, but as for my verizion 4g wifi hotspot, it dont work well, even if im on top of my 4g router, i can run my usb wifi chip with no problems even when i am far away from both routers, i hope acer can help me out when i call them tomarrow about this.

thanks for posting this by the way

OMG!  You are a genius and so very good to post your findings.  

I have been fighting this problem for over 4 months, and have cleaned the Registry, defragged the disk, purged unneeded background programs, etc, etc but all to no avail.  :-(

Finally in frustration tonight, I plugged directly into my router via ethernet cable and discoved the computer was clearly capable of good performance, thus pretty much proving that the source of the issue was in the wifi adapter.

Did a Google search on the subject and found your posting on my 2nd try.

Made your suggested settings changes to the wireless network adapter and OMG there was an order of magnitude difference in performance between speedtest.net measurements made before and after the changes.

Web browsing is now a pleasure again, and we don't have to wait for 5 minutes for emails to update everytime we fire up Thunderbird (mails now appear in 3-5 seconds!).

We are VERY HAPPY CAMPERS thanks to you.

Thank you for your post!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!   :-)

Thank you a LOT !!!

Unfortunately it all fell apart.

The "improvement" only lasted a day, or so, and quickly went from bad to badder!

Never knew what the next power on restart was going to bring in terms of performance.  It finally got to hardly better than a dial up modem.  For anyone too young to have experienced those, the maximum speed was 50Kbs!  :-(  

Added an external USB wifi adapter for temporary fix and this week sending the whole dang computer back to acer to be repaired.

It has been a disaster!

Which model 572 or 572G?

For me, it wouldn't be worth the hassle of sending it back when I could replace the wifi card for about $20.

This machine is a Laptop and thus I assume there is no "card" but that the Broadcom wifa Adapter is an integral part of the circuit board, and thus not "readily" replaced.    [:-)}

I haven't looed to be sure, but I've never had a laptop before with swappable cards like a "tower" system.

The wifi card is in this photo, just below the speakers, with the long barcode on it.

OMG!

That is a first in my experience.  :-)  I've never encountered replaceable cards in a laptop.

Where does one purchase that wifi card?

I agree it would be much simplier to replace that than ship the entire Laptop back and the cost is virtually the same, if not cheaper!!!

Much thanks.
