External antenna on mini PCI WiFi card
« on: 24-March-05, 15:08:30 »

Hello,
    The stock mini PCI WiFi card on the MEGA 865 has terrible range.  I can not connect to an access point beyond 20 feet.  Can an external antenna be added to the card?  Does someone sell a mini PCI WiFi with external antenna?  The new MEGA 865 PRO has an external antenna!!!!!  Where can I buy this 865 PRO WiFi card and antenna?  My PCI slot is filled and USB keys seem to have about the same range. 
     In another computer I have a D Link PCI card 802.11 a/b/g with external antenna with excellent signal at 100 feet.

Thanks for your help!

I've taken the normal radio antenne (because i have a other tv card with radio and antenne) and taken the mini pci card and linked both up to each other and now i have the radio antenna as a wifi antenna wich has a range of +- 100 M measured

    here its a image in which you can see the mini pci with the wi fi card. (NOT the perpendicular block, this is the RADIO)

    i think im going to add some changes to my mega 180 MOD and im going to add also a wifi antenne. A how to guide >HERE< sorry not in english  :-P) ask google

    i will be thinking in how to connect the antenne to the wi fi card for the next 2 hours lol (not truth) i will post here what i conclude :)

    hi there
    i got myself a wireless-g/b/a mini-pci centrino card to replace with the current wireless-b card in my MSI 865 deluxe

    I managed to pluck the card out of the mini-pci socket, but the antenna wires are still on the card :( so it wont come out

    can i cut the wires and reattached them? i would have thought that would disrupt the wireless signal of the new card tho

    i dont want to remove all the cages..as that seems too much work

    does some1 have a guide/pics to replace the card?

  • normally the two antennae unplug from their connectors on the mini-pci card

    its exactly the same setup as you would follow when replacing a mini PCI card in a notebook/laptop

  • Try to use a pair of tweezers to detach the antenna cables. I would not advise you to cut the wires!

  • it may be a signal problem, try setting your router/AP to a different wireless channel

    nope...no change when changing wireless channels

    i have mapped a network drive on my MSI MEGA...so it can access movies/pictures etc from another PC
    whenever i click (in My Computer) on the networked drive (named it M: ) it takes about 30 seconds to connect...also the internet takes just as long before anything appears....i have "Reconnect on Log-in" checked on the mapping
    after *finally* a connection is made..then the connection drops off after a few minutes....as if the connection is meant to be only active when used then shuts itself down to save power or something

    i checked out the "View Wireless Networks" and discovered it had lost connection with the router
    i click on "Refresh" and it still says "No Networks Available"....im lost here....
    either it takes ages and lasts a few minutes to connect...or it doesnt connect at all

    im talking about a wireless network here...heheh

  • oh i get occasional problems with my wireless network just like yours

    (in fact just happened again!)

    try using a Site Monitor utility (there may be one included in driver utility) to see if there are any other wireless networks nearby that may be interfering

    select your channel to be as far away from others as possible

    restarting your router is a useful (if annoying) fix

    also check you don't have any cordless phones, microwave ovens etc affecting wireless signal strength

    there are no other wireless networks in my street
    restarting the router doesnt do anything useful
    i changed the channel number for wireless..no difference
    i have a microwave..but hardly eve use it and a cordless phoe which does not run on 2.4Ghz..

    im thinking its perhaps a driver problem or hardware problem..but dont know where to start..

    my wireless connection seems very fast...reaches 54Mb/s but the connection doesnt stay on long enough..only a few minutes at a time

    *ggggrrr*  :think:

  • try moving your rig and the router to various positions in the house, to see where you get the best signal. i installed my wireless network at home about 2 weeks ago and had the same problems, till i found a good location in the house for the router. the positions of the antenas from the router also makes a big difference, since they are probably omnidirectional antenas. another thing that i found to be usefull is to place the router at aprox. the same vertical level as the wireless cards in the computers. if after this it is still a no go, i suggest you try purchasing some high-gain omnidirectional antenas (preferably >= +9dBi) and replace the ones that you have on the router and on the wireless cards.
    good luck.

    ahh ha! success...

    I got new Intel drivers for my wireless Mini-PCI card from the Intel site itself.
    It now is very stable...transferred more than 5gig at once without dropouts :)
    Only problem is that the speed is sacrificed a bit...i was getting slightly higher transfer rates with the original drivers(which came with the card).. now im getting max 2MByte/s(16Mbits/s) with these new drivers....also Windows can see the wireless network connection as "Status:Excellent"..so im pleased with the stability

    Can any1 explain how(even when 2 wireless-G devices are sitting next to each other) they can never reach 54MBit/s ??? So then 108MB/s must be an absolute load of crap ..and not even reach 54MBit/s properly

    I should be getting around 54MBit/s ..after all why say its 54MBit/s when its not ....grrrr

    Hi, I'm having trouble with my wifi connection (I have a 865 deluxe and a 180 and both have a very bad wifi range it seems)
    So
    I've taken the normal radio antenne (because i have a other tv card with radio and antenne) and taken the mini pci card and linked both up to each other and now i have the radio antenna as a wifi antenna wich has a range of +- 100 M measured

    I'm interrested in this method if possible. Has any one infos ?

    Thanks

    About the speeds...
    In my CISCO class, they told us that half of that speed is reserved for data transmission or encryption.. thats why it always goes a little slower than it says. In reality, I guess it is around half. So, for 11mb/sec, figure around 5.5mb/sec, and so on.. Sometimes with newer driver and optimial conditions without interference, you might get your actual speed as advertised.
