Hey everyone,

 

Essentially my computer is having a software issue or hardware issue I can't tell. I contacted Toshiba and followed all their steps and they concluded that it was a Software issue. My computer is a Toshiba Satellite using a Realtek WiFi card.

 

I've tried updating drivers. I've tried uninstalling drivers and reinstalling them. I've tried resetting my modem. It's not my modem. It's my machine.

 

Please help.

Hello Agent Shark,
 

 

I'm sorry to hear of your networking issue.
A few questions to help us begin our troubleshooting:

1)  Did it ever work properly?

2)  If so, did anything change between when it worked and when you first noticed the problem?  (updated drivers, hardware/software installation, etc?)

 

3)  Can you please give us a little more detail on the actual problem?  Can you connect at all (even temporarily)?  How often does it drop?  Can you trigger/cause the problem by doing something?

4)  Do any other wireless devices have this issue in your network?

Interference

For more details on this topic, see Electromagnetic interference at 2.4 GHz.

Wi-Fi connections can be disrupted or the internet speed lowered by having other devices in the same area. Many 2.4 GHz 802.11b and 802.11g access-points default to the same channel on initial startup, contributing to congestion on certain channels. Wi-Fi pollution, or an excessive number of access points in the area, especially on the neighboring channel, can prevent access and interfere with other devices' use of other access points, caused by overlapping channels in the 802.11g/b spectrum, as well as with decreased signal-to-noise ratio (SNR) between access points. This can become a problem in high-density areas, such as large apartment complexes or office buildings with many Wi-Fi access points.

Additionally, other devices use the 2.4 GHz band: microwave ovens, ISM band devices, security cameras, ZigBee devices, Bluetooth devices, video senders, cordless phones, baby monitors, and (in some countries) Amateur radio all of which can cause significant additional interference. It is also an issue when municipalities or other large entities (such as universities) seek to provide large area coverage.


Even bad electrical connections can cause broad RF spectrum emissions.

I've fixed the issue by refreshing the machine along with purchasing a powerline adapter. So far signal and wifi capability is MUCH more powerful.
