This article applies to Windows Vista, 7 and above.
Problem
When your laptop is not connected to a power source, you experience problems connecting to the internet using your wireless connection. The internet may be slow or keep dropping out. You may also see a message stating “Limited connectivity”.
Cause
This can be caused by connecting to a router or hotspot which does not support the 802.11 power save protocol. Also, if you have a Toshiba laptop that was original purchased around 2009 and with a Realtek wireless card, there may be a bug in the currently installed driver.
Solution
Solution 1
- Click the Start button.
- Type Power Options and press Enter.
- Click Continue if prompted.
- Click “Change plan settings” under the power plan that is currently selected.
- Click “Change advanced power settings”.
- In the Power Options box, click the + next to “Wireless Adapter Settings” to expand it.
- Then click the + next to “Power Saving Mode”.
- In the list that appears next to On battery, select “Maximum Performance”.
- Click OK.

Solution 3
- Click the Start Button.
- Type “Device Manager” and press Enter.
- Click Continue if prompted.
- Click the [+] next to Network adapters.
- Right Click on “Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC” or similar Wireless card.
- Click Properties.
- Click on the Advanced Tab.
- Click on 802.11d.
- On the right hand side change the drop down to Enabled.
- The following steps are optional but may help:
- Select TX power level.
- On the right hand side change the drop down to 100%.
- Select Wireless mode.
- On the right hand side change the drop down menu to “IEEE 802.11b/g”.
If you regularly stream music to other computer in your house do not change these options. Although 802.11b/g are more stable protocols, the maximum speed is 54Mbps.
- Click OK.
Your network will disconnect momentarily, then reconnect.

Damn…!!! if power saving option turns off the WiFi, they shouldn’t turn it off to save power, or at least give users some indication that the wireless has been switched off to save power, instead of giving a cryptic “Limited Connectivity” message.
Very poor form on Microsoft…!!!
