To defeat the most wireless problems

Poor reception, full frequency band, hanging router, forgotten passwords: Comfortable wireless networks are indeed, but there are always breakdowns and interruptions who spoil the operation of the wireless network.

Poor Reception: External WLAN adapters

Although the aluminum and magnesium casing of notebooks and Ultrabooks look elegant, acting on the internal WLAN antennas but as a shield. Cheap, external wireless adapter, connected via USB, bring significant performance improvements in wireless network. Even better: Use extract a USB connection cable one to two meter long, in order to align the external wireless adapter regardless of the laptop and therefore can often decisive dBm signal strength. An external adapter also allows the upgrade of the client on the 5-GHz frequency band of 802.11n / ac, if the wireless router offers this standard.

Login failed: Systematic check

If the wireless network of the router is set up correctly,but the connection establishment is still fails, then you are looking for the possible errors systematically.

1. In most cases, only the WLAN password is entered incorrectly, for example by an unsuitable keyboard layout.

2. Does the password special characters? It happens that the firmware of a router or device does not support some ASCII characters. As part of wireless passwords taboo are all forms of braces, the dollar, percentage, exclamation and pound signs and slashes.

3. If a MAC filter on the router active? See the security settings of the wireless network on the router to see if a list of allowed MAC addresses excludes new clients.

4. Supports the client the chosen wireless standard? For routers with dual-band (5 GHz and 2.4 GHz), you should check that 2.4 GHz was turned off accidentally.

5. When a PC, laptop or smartphone does not come into WiFi, then test the access to a second device. Often, the WLAN configuration is fine, but the signal strength is no longer sufficient in the problematic client for registration.

6. To exclude the wireless router as the source of errors, helping an alternative hotspot. A smartphone or tablet with Android sufficient because hotspot capability provides Android since version 2.2. Go to Android to "Settings -> Wireless & networks". One of the sub-points is "Tethering and portable hotspot". Even with Apple devices from iPhone 4, iPads third generation and the iPad Mini, you can configure a "personal hotspot" in the Network Settings. Importantly, WPA2 encryption (WPA2 PSK) for realistic testing conditions to choose.

More is better? Not in the transmission power

Some wireless routers can adjust the transmission power in percentages or in milliwatts (mW). If clients can not connect in a corner of the apartment, then possibly is just too large transmission power problem. A high level does not automatically mean better reception - on the contrary, strengthen interference likewise, and the signal quality can be even worse than at lower transmission power. Check, if available, the router settings to transmit power, and you resolve this without a trial basis.
