Fejlsøgningsscripts søges

[Viborg]

Efter at jeg fik banket en ekstren antenne på, for at få bedre signal til til det trådløse netværk er det blevet meget bedre...men åbenbart kun for Windows.

Jeg kan sidde det samme sted og starte op i henholdsvis i Win7 og Ubuntu 10.10 og der er står forskel på signalstyrken. win7 banker derudad med fuld skrue på signalet, mens Ubuntu får skal jumpstaters med den gamle router og derefter kan jeg hoppe over den ekstrene antenne og forsætte derfra. Man Ubuntu kan kun trække en streg i signalstyrke og flader ud efter en 10 minutters tid.

Så lige nu søger jeg nogen fejlsøgningsscripts, hvor man kan se hvad der er galt og hvad der skal gøres for at løse dette

Højer klik på forbindelses ikonet og vælg forbindelsesinformation, se vilken driver og hastighed der bliver brugt.

Hovderouteren hedder "tdc" og den router hvor den ekstrene antenne er monteret hedder: "her" Men jeg har ikke kunne få forbindelse til "her" i løbet af dagen, selv om det er det signal der skulle være stærkeste.

Description: mode switching data for usb-modeswitch
Several new USB devices have their proprietary Windows drivers onboard,
especially WAN dongles. When plugged in for the first time, they act
like a flash storage and start installing the driver from there. If
the driver is already installed, the storage device vanishes and
a new device, such as an USB modem, shows up. This is called the
"ZeroCD" feature.
.
On Debian, this is not needed, since the driver is included as a
Linux kernel module, such as "usbserial". However, the device still
shows up as "usb-storage" by default. usb-modeswitch solves that
issue by sending the command which actually performs the switching
of the device from "usb-storage" to "usbserial".
.
This package contains the commands data needed for usb-modeswitch.

Description-da: network management framework daemon
NetworkManager attempts to keep an active network connection available at
all times. It is intended only for the desktop use-case, and is not
intended for usage on servers. The point of NetworkManager is to make
networking configuration and setup as painless and automatic as possible.
If using DHCP, NetworkManager is _intended_ to replace default routes,
obtain IP addresses from a DHCP server, and change nameservers whenever it
sees fit.
.
This package provides the userspace daemons.

Ok, det er enlig bare meningen du skal poste linket så det ikke bliver sådan et kæmpe indlæst (og undgår smilys) men det går nok. Jeg er ikke lige nok inde i wifi til at kunne se hvad problemet kan være.

jeg sider nok med det samme problem her kan jeg se min hopper os af nettet efter 10 min http://paste.ubuntu.com/563773/

Kan det have noget at gøre med at Ubuntu og min Netgear ikke kan "snakke ordenligt sammen"?

Vil gerne hører om der er andre der har problemer med Ubuntu og Netgear Wifi

Generelt skal du skrue ned for hastigheden, så der bruges en signal-indkodning der er mere robust over for støj.
Du kan også i nogle tilfælde skrue op for sende-effekten, både på routeren, og i Ubuntu.
Det kan også være relevant for at skifte kanal du sender på, så du ungår interferens med andre der sender på samme kanal.

Du skruer på hastigheden og sende-effekten i Ubuntu med iwconfig kommandoen, du må selv skrue parametrene på den kommando sammen.

Du kan få en liste af netværk med iwlist.

Kanal skift, og sende-effekt fra din WLAN router foregår fra dens browser konfiguration.

Vigtigt: Sørg så vidt det er muligt at der kun er luft imellem din computeres antenne og dit accesspoint (WLAN/WiFi routeren - det kaldes optisk sigt. Metal og (træ som indeholder vand) skærmer for radio signaler, så har du aluminiums- eller træ- persienner så træk dem op så signalet kan komme forbi, ellers bliver det absorberet og/eller reflekteret. Mure med jernbeton kan være uigennemtrængelige for Wifi/WLAN, og 3G/UMTS, Bluetooth og så videre signaler, fordi der er metal i muren.
