It seems as though my linksys wireless g router

I had this same Router (replaced a Hub with this Router when I bought a wireless laptop & bought this G-Router to get rid of all the cords). I had noticeable problems within a month and upgraded to a Linksys Wireless-N Router (a little more money, but well worth it!!). I upgraded to model#: WRT400N and it has proven to be quite durable, dependable, and a reasonably priced model (bought mine for less than $60 in May of 2009). I think my Router (Linksys WRT400N) may still be on Retailer shelves, but newer models are likely being offered at higher prices (search for the WRT400N on the net, and I'll bet you can find it for <$60 right now). Good Luck!

Dear Check below things
1:if the distance between your router is more tahn what is it actually has to be,u might encounter this problem.u will have a sucessfull wireless network somwhere within the range of 35-40 feet and there are certain limitations if u are promised tht your router will broadcast signals upto 100-150 feet.most of them are just on papers.but u do have routers in the market which have the capability but the network has to be in a straight line and there should be no walls in between always remember tht wireless signals will,not work vertically they might (but u will have issues) works good in a horizondal way
2:do not keep the router inside a room and try to acess it from another room.your wireless signals are not strong enough to penetrate your walls or ceiling or flooring and be available to your computer
3:do not have devices like a cordless phone,a microwave owen or a mobile phone right next to the router or next to the computer tht you are working on.this will cause interference to the wireless signals and you will see the connection dropping whenever you you operate these devices.
if you cannot avoid any of these devices then try changin the channel number on the router.contact the router manufacturer.if this is done the router starts broadcasting signals in a different frequency.u might face another problem here.you card actually has to respond to the signal given byt the router and has to chage its channel number automatically.for some reason if this does not happen you will have to do this manually
like in some (dell cards)letme tell you changin the channel number does work miracles
4:try updating the drivers for the wireless card.for this u need to contact the hardware manufacturer or you can contact the computer manufacturer.you can also download the drivers from their respective websites ,in most cases this does fix the issue.
5:identify the software/programme that your wireless connection is using.in general if you are runnning windows xp,WZC(wireless zero configuration) will take care of your connection.or if your are using the utlity of the card ,WZC will be disabled and the utilty will take care of the connection.
possibilities are there that the card utility itself can cause a mess.if u are using WZC make sure that the utilty of the card is not under the start up group.if this is the case then whenever you restart the computer your connection will be lost and you wil have to reconnect manually.this is because when u restart the computer the utlity software will force itself to manage the connection thus disabling WZC.
6:setting up high security to your network might at times cause u to loose the connection wep is a good form of security but wpa causes a problem especially when u have upgraded your OS to sv pack 2. wpa is actually a very good form of security
but has a lot of complications
it makes use of the a principle called hashing algorithm ,
the password tht u type in is scrambled every __ seconds depends on the refresh rate tht u have set which slowers the connection and might even lead to the connection dropping.
7:make sure you anti-virus programme is not the one which is causing the problem.a good antivrus programme comes with a built in firewall which ofcourse protects your computer but blocks your connection,if this is the case you have a workaround .you have to register the ip address of the router with tht anti-virus programme. (like in mcafee you have an option as trusted ip's.you might also have a similar option in norton as well.if possible try and disable personal firewall it helps really !! dont worry bout the security your router has got an inbuilt hardware firewall and tht'll take care of things.
8:mixing diff brands on the network does'nt really cause a problem,but i would recommend u going for products from the same company so tht u need not keep shuttling from one company to the other for support to find out if their hardware is the one tht is causing the problem.coz in networking evrything is interlinked.
9:also chk which part of your netowrk is causing the problem ,see if it is the router or the card.if it is the card then,you have options like updating the drivers if it has got something to do with the router then you can try upgrading the firware.contact the manufacturer of the router for this.
10:power managerment does come into picture here.u can actually change the settings under the properties of the wireless card (advanced settings) set the power managerment to manual set it to maximum.also u have an option allow windows to turn off this device to save power,uncheck this.
if u are running on battery this option disables ur network card when ur charge is running low.
