Hi fellow tweakers! I am about to embark on a mission to upgrade the performance and functionality of my WRTSL54GS router... I plan to first upgrade the stock "fixed" antenna to the same connector type as most WRT's; the female RP TNC. Here is a pic of what I think Im going to order: I searched the forums but only found "talk" of doing the mod... no actual reports. The side of the unit where the fixed antenna is located looks like an ez mod with my trusty dremel. Here are pics from the autopsy done by Toxic: and a close up: Has anyone done this mod? If so can you give details and results. If not, why hasnt someone tried this? Pros/Cons? Also, I am good with soldering... just havnt done anything with RG174U coax b4... any words of advice? Should I cut the current antenna wire, b4 I solder on the bulkhead? If so what is the optimum length? After I have modded the antenna connection, I am going to get a decent 7-10 db ant... any suggestions here? Finally I will upgrade my firmware and OS to one of the Linux based OS's... I believe it's DDWRT? or what do you all use and why? Do any of these alternate OS's provide for the USB storage function now? Last time I had checked the SL54GS was too new and the function had not been added. Thanks in advance!
