Weak wifi connections?
2013-09-17 3:27 pm
Recently I have been having wifi issues with my laptop. I just got it back from a repairman several days ago and I noticed this issue when I tried to connect to my internet at home. The laptop had difficulty finding the signal while I sat on my bed less than 2 meters away from the router and when it did connect, it fluctuated between no bars and 2 bars of internet. I had to place the laptop right next to the router to get 3. I cannot connect to any wifi outside of home anymore. I think the repairman might have done something while trying to replace the keyboard.

The repairman may have disconnected the internal WiFi antenna (if there is one).The WiFi adapter drivers may also need updated.
If neither solution works, I would buy a inexpensive high gain USB WiFi adapter.
Either of these are good choices,
TP-LINK TL-WN722N Wireless N150 High Gain USB Adapter,150Mbps - http://www.amazon.com/TP-LINK-TL-WN822N-Wireless-External-Antennas/dp/B00416Q5KI/ref=sr_1_7?s=electronics&ie=UTF8&qid=1379431483&sr=1-7&keywords=usb+wireless+adapter&tag=excharge-20
TP-LINK TL-WN822N Wireless N300 High Gain USB Adapter, 300Mbps - http://www.amazon.com/gp/product/B00416Q5KI/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00416Q5KI&linkCode=as2&tag=excharge-20
No matter what you decide to buy, as far as the brand goes, the brand is not as important as the model. Some manufacturers release a good model but the next is crap. I would look at the Amazon reviews of models that interest you. Even if you don't buy from Amazon the reviews will tell you a lot about which models to avoid. Look for at least 15 or more reviews with a 4 star or better rating. Read a few and you will gain a lot of insight on the capabilities and performance of the product..
That being said,
Often signal strength (bars) displayed by your device can be misleading, WiFi interference can cause havoc with consistent speed.
Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc.
All of these factors will affect your actual wireless range. As wireless connection quality varies the WLAN connection speeds are renegotiated. The connection may start at 150 Mbps and end up at less than 20 Mbps or drop entirely.
The WLAN connection speed is only between the device and the router, you are still limited by your WAN Internet speed provided by your ISP.
Good Luck...

Probably there is problem on wireless adapter driver on laptop. Go to wireless adapter vendor website to find out if there is latest driver, uninstall the existing one and install the latest driver if it's available.
Hope this helps.

this happens to me when the weather is crappy or there is something outside blocking the signal.
