WLAN problem solved, FSG WLAN functions are now completely stable!

1st Initially, I had a relatively unsuccessful better external antenna with approximately 1.5 m cable-round characteristic concerned and connected (D-Link 2.4 GHz 5dB), the fluctuations were still present ...

That was probably not going to work, so unceremoniously I dismantled the FSG and after 1.5 h cautious labouring behold ...

My solution:

First, I dismanteled the questionable wireless card (own investigation) from the FSG: Only the Main jack is allocated with the outside antenna on the back of the FSG also ... the existing AUX jack is unused / is not allocated (I had expected an integrated antenna casing).

For a wireless router, it is vitally important that the best receiver situation can be determined independently. Therefore, the connection of the existing AUX jack was imperative. Each mini-PCI WLAN modules has usually two antenna jacks. If only one antenna in / on the router is present, it should be connected to the "MAIN" designated socket, as is the case in the FSG. If there's a second antenna, then connect it to the "AUX". Then the WLAN MINI PCI module switches from MAIN to AUX depending on the reception in each situation. This procedure is called Diversity and, in general, gives a much more stable wireless connection.

Then, I have tested the stability of my MINI PCI card; Vendor: pci 0x11ab "Marvell Technology Group Ltd.." Device: pci 0x1faa "88w8335 [Libertas] 802.11b / g wireless; revision: 0x43; IRQ: 10; modules alias" pci: v000011AB00001FAAsv000011ABsd00001FAAbc02sc00i00 " with the help of my laptop ACER ASPIRE 1362 debugged and behold, the card works very stable.

So summarily FSG3 rebuilt the (extended)

2nd Pigtail a wireless adapter on eBay auction for about € 8, --

3rd The adapter as the existing but exactly on the opposite side, so when the FSG at the bottom at the rear, exactly centered in the existing slot used (drilled a 6mm hole). The inside plastic bridge to the rear of the surface was removed and the gold threaded Jack put into place (otherwise, it is too short).

4th The Marvell MINI PCI card reinstated, but the existing antenna on the AUX and the new antenna plugged in on MAIN.

5th Before the Assembly, on the fourth pole of the upper housing FSG shell of the outer reinforcing bridge will have to be removed, so that the posts between inlet antenna jack and extension board (with the SATA interface it) fits. Caution: very carefully then re-assemble half of the housing so that the red SATA cable is not damaged, or even one of the solder joints fragile SATA cable tears.

6th After assembling connect the new D-Link antenna to the new antenna connector (MAIN), and connect the old FSG antenna to the old port.

Then start the FSG ... And rejoice ... :-)

Addendum: Some craftsmanship and costs in the amount of approximately € 30, - are needed for this solution.
