Wireless: problemi con Hard Disk NDAS

[cicciotto]

Ciao a tutti,
ho comprato un hard disk NDAS, l'ho attaccato
con il cavo ethernet al router e ho installato su tutti i PC i
drivers e il software.
Ecco il problema: se collego il PC al router con il cavo ethernet
il software rileva l'hard disk in rete e il tutto funziona correttamente,
se invece mi collego con la scheda wireless il programma non vede l'hard disk (risulta sempre offline)
Qualcuno di voi ha suggerimenti per la configurazione del router o del
pc o qualsiasi altra cosa per farlo funzionare (uso windows XP)?

Qualcuno ha qualche consiglio?

Riesegui l'installazione del software quando sei collegato in WiFi, se l'hai installato e configurato, collegato in LAN, è normale che quando non attiva la connessione LAN te lo dia in OffLine.

Quando l'ho collegato e installato il software per la prima volta stavo operando tramite wifi, ma non riuscivo a rilevare l'hard disk in rete. Quindi ho collegato il pc al router con il cavo ed in questo modo il programma ha immediatamente rilevato il ndas.
Quindi non credo sia un problema di installazione del software anche perché ho poi installato l'ultima versione del software, ma anche questa rileva l'hard disk solo se il pc è connesso con il cavo.

Altri consigli?

Ho la sensazione che ci sia qualche problema al TCP/IP delle schede di rete.

Sia la scheda ethernet che la scheda wi-fi sono impostate con la stessa classatura ip?

Sono in DHCP oppure con indirizzi statici?

Mi scuso
Non l'ho ricevuta o è passata inosservata tra le tante, riprova a rinviarla.

L'indirizzo ip viene fornito dal router, ha il dhcp attivato.

I'll paste in some general wifi tips for NDAS. It is rare, but you might have a wifi card that does not work by NDAS, since it is a USB adapter.

Focus on these things:
Is LPX Protocol installed on your wireless adapter?
Do you use the MAC address filter on your router?
Are you using any repeater or wireless bridge?

In general, the connection to a wireless NDAS device is like a wired one. You can only test to verify if the wireless devices are not connecting by trying the connection via Ethernet. If the wired connection does not have any interference or lost connection, then you know it is the wireless operation.

If the wired connection also has some connection dropping, you can try to maintain the disk with chkdsk and de-fragmenting.

If there are still instable connections, then your hard disk can be also failing.

If you discover the wireless is the only problem then there are some more in-depth issues to look for, but not altogether NDAS related. What follows are descriptions of the main problems that we have found with wireless NDAS traffic over the years.

Network Adapter Drivers
Some users upgraded their PC to windows 7 and found that some hardware was not officially supported by the manufacturer for use in windows 7. This happened to wireless connections more than Ethernet connections, but it has affected both. If you are using windows 7 on a computer that has previously had another windows version installed, visit the manufacturer of each hard ware device, video card, wireless card, and Ethernet card to see if you particular hard ware has newer drivers or firmware available. The version release should be some time after Sept 2009, when Windows 7 was officially released.

Protocol Filter
The NetDISK uses a proprietary protocol to connect to and from the device and computer. This protocol is called a "layer 2" type protocol so you may want to see if your router and your wireless network card supports this protocol or all types of protocols. Some routers allow Protocol Filtering. but depending on the wireless router you have you may not have this setting or it may be called something else in which case you may need to contact the router manufacturer for details about it. We recommend that you completely disable this so that all protocols are allowed to pass through. However, If you want to enable specific protocols, the LPX Protocol has the network signature: 0x88ad which you may be able to add to the list of allowed protocols.

If you use a removable wireless adapter, it is possible that the LPX Protocol is not installed on your adapter.
You may see if it is installed on your network card by the following instructions:
WinXP: Start -> Run -> Type ncpa.cpl -> Click OK
Vista / 7: Start -> Type ncpa.cpl _> click OK
In the Control panel Right Click your network card:
Scroll Down the window to look for LPX Protocol
If it is not installed click on Install
Choose Protocol
Click Add
Choose "Have Disk"
Browse to the following location:
C:\Program Files\NDAS\Drivers
Choose "netlpx.inf"
Click Open
Click OK
Click OK.
Once the protocol installs, you should be able to communicate with the NetDISK.

MAC Filter
The second thing is MAC address filtering, depending on your security measures you may either want to disable this or obtain the MAC address for the NetDISK and allow it to pass through. In order to obtain the MAC address you can mount the drive by Ethernet wire and check the properties tab on the NDAS Device Manager drop down menu under the mount / dismount options. Open the Properties page can choose the Hardware tab to see the MAC address for your drive. Copy it and type it into the MAC address filter on the router.

Single Speed
One other possibility is to set the "Auto-Switch" mode to one standard, In many cases "G" so that the router will use only one standard to move traffic.

Security Encryption Method
It was reported one time that running the wireless security in the "Auto Select" mode, prevented the NDAS connection. When the user fixed the security on "WPA2 Personal" mode, the NDAS device was detected.

Wireless Bridge or Signal Repeater failure
In most cases the wireless bridge and repeaters will not work with NDAS because those devices corrupt the NDAS device's MAC Address based communication path. Some work workarounds exist, but we do not support them as they require reconfiguring the network hardware which can ruin the hardware if done incorrectly.

The device and bridge below have been reported working with NDAS "out of the box" in case you were looking at of updating your network hardware over all.

Then look into improving the overall signal strength. Here is one example:
