Resolve the WLAN problem

Some FSG users have problems with WLAN. Lazyuser was one of them. If you have similar problems, maybe you can fix it by this way.
- But, be carefull because this will make you LOSE YOUR FREECOM WARRANTY
- The Wireless connection is not stable. Sometimes works perfectly, sometimes you loose the connection.
- When you check the signal with Networkstumbler (Windows) or Network Manager and Iwconfig (LINUX), you see:
- strongly fluctuating signal strengths from the FSG
- fluctuating throughput rates up to the connection loss.
- Using other Wireless device (as other Router) does not have those problems, so you are sure that those signal problems comes from FSG.
Researching the causes
- Is the WLAN driver? Is there an alternative driver for the wireless chip in the FSG3?
- There is something about this. It resolves some things.
- Where will ask the power management for the WLAN driver?
- Bring a dish may change mitigation, the mirror reflection perhaps too high?
No one of this brings the solution...
Our friend, Lazyuser dared to dismantle the FSG itself. In the inside, he founded the Wireless Card of the FSG.
Their characteristics are:
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
- He saw that only the Main jack is allocated with the outside antenna on the back of the FSG also ... the existing AUX is... is not allocated (One can expect to have an integrated antenna).
- For a wireless router, it is vitally important that the best receiver situation can be determined independently. Therefore, the suppression of the existing AUX jack imperative.
- Each mini-PCI WLAN modules are usually two antenna jacks. If you only one Wavecatcher in/on the router can find, it concludes that the "Main" referred socket, as in the FSG.
- If there is a second antenna, it comes at "Aux".
- Then the WLAN MINI PCI module can decide the best antenna depending on each situation.
- Now, it was time to check the stability of the Wireless card with the help of his laptop ACER ASPIRE 1362 debugged and behold, the card works very stable.
This is the Lazyuser solution:
- Pigtail a wireless adapter on eBay auction for about € 8, --
- Adapt it 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).
- The Marvell MINI PCI card reinstated, but the existing antenna on the AUX and the new antenna plugged in on MAIN. (The best anttena you have, in the MAIN).
- 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.
- After assembling connect the new D-Link antenna to the new antenna connector (MAIN), and connect the old FSG antenna to the old port.
This is the Sdool solution:
- Instead of making a new hole, the RP-SMA connector for the wireless antenna is passed trough the hole for the Kensington Lock.
WLAN problem solved, FSG WLAN functions are now completely stable!
Then start the FSG ... And rejoice ... :-)
- Some craftsmanship and costs in the amount of approximately € 30, - are needed for this solution.

Attached you will find some pictures of my FSG, hope the links will work...

As sdool user experience, this works fine with firmware 3.1.29! He tested it with later firmwares (betas) without much success. The Wifi Client gets properly connected but there is no throughput of data.
With 3.1.29 the connection is like it should be, even with his HP Laptop with the Intel Pro Wireless 3945 ABG wifi card, which is mentioned on this forum as not working with the FSG.
