Title: Limited Or No Connectivity
Post by: mikewithaprob on November 14, 2006, 04:58:26 PM
My family has 4 computers in total including mine. Im contemplating whether to put my computer downstairs and have it running wireless. But, the problem is everytime I try to access the wireless network is says: Limited Or No Connectivity Due to the router not assigning the computer an IP address.
Im assuming these questions will be ask so I'll answer the ones I can: Computer Specs in Sig, Linksys WRT54GS router, And my wireless card im not sure what it is because it came with the computer when I bought it. But it says 802.11g Wireless MiniPCI Card. All the computers running wireless had difficulty getting on to the network, so we had to hire someone to do it. I'd rather not hire someone because this is more of a convenience thing, then a must have.

Also, I just remembered I use Avast as an antivirus don't know if it'll help, and I have windows firewall.

i get that problem sometimes... all you have to do is resett the router..


turn off all computers

unplug all wires from the router

there should be a lil button near the power on the router push that button in for 30 seconds. then plug everything back in and turn on all of the computers and see if there get the internet.

if you want to put the sercurity stuff back on(if you had any) i will be glad to help you do that

Simply rebooting the router by removing the power and plugging back in should take care of that. No need to reset to defaults.

Thank you for the replies. I've already tried resetting the router, and the modem, by unplugging it. Im not sure why it does this.

Is the router the same brand as your wireless network cards?

Why not try giving the wireless network cards static IP addresses?  That solves lots of problems.

Post by: mikewithaprob on November 15, 2006, 01:34:32 PM
Do you do that in the router settings?
Title: Re: Limited Or No Connectivity
Post by: Rob Pomeroy on November 15, 2006, 01:59:52 PM
No - on the network settings for each wireless card on each PC - under TCP/IP settings.

See the networking FAQ.

then i reset the WRT54G. everything back to normal, both my pc and laptop can connect to internet.
after few hours then the problem back again. i have to reset the WRT54G few time a day.
is there is a posibble connection problem between my motorola cable modem and my WRT54G.?"

when i loose connection, the status at my linksys monitor show connected.my WRT54G look normal, just the internet activity LED blinking very slow, about 2second,  then i  ping my WRT54G, starting i get 4 or 5 request timeout, then i get 4-5 reply, then timeout again, about 4-5 time then get reply again.
after i off the router power and on back, everything back to normal. wireless and thru LAN cable also same.

The "limited or no connectivity" relates to DHCP, probably.  But the failure of the internet connection will either be a problem with your cable service, or possibly a failure of the cable modem.  See if you can try using a different cable modem.  These things are generally left switched on 24/7 and they do die, eventually.

4 things:

1) Are you using the linksys conection utility I have had many problem with it in the past. If so post back for more detaled instructions. DO NOT TRY TO UNISTALL. (WILL SCREW YOU UP BIGTIME)

2) Is the signal encripted, this can degrate the signal and if your signal strength is low it can cause the rouyer not to assign an I.P. address.

3) Did you already tey setting a stack I.P. (Make sure it is not already used.)

4) I know linksys has 24/7 tec. support. Face it they are more fimilure with there system then we are. (You must be very relazed and rested befor doing this step.) ;) ;)

i have both my pc and laptop connect to router, my pc is thru wireless, laptop thre LAN cable.
when my linksys monitor show "you connected to the access point but the internet cannot be found." both my pc and laptop show the same thing. both can't connect to internet,
as i said b4, i power the modem and on back. still no respond.
power off the router and on back, both can connect again.

what i suspect is the router.
before that i use DHCP, now i change to static ip. still didn't solve my problem.
signal strengh between good to excellent.
using channel 1
wireless security = wpa2
static ip
pc ip=192.168.1.108
laptop ip=192.168.1.107


the message "Limited Or No Connectivity " only show up few time when i leave my pc running in the morning and  when i come back from work after 10 hours i saw this message. it's not frequently happen. but this "you connected to the access point but the internet cannot be found" happen everyday.!
i also try use different security method, even use mac filter,  result same.
i already post this in linksys forum, http://forums.linksys.com/linksys/board/message?board.id=Wireless_Routers&message.id=16070&jump=true#M16070
 
seem not much help. so i look for other advice from here.
my pc spec
P4 2.8
1GB RAM, 512+512
windows xp pro sp2(updated)
internet connection : linksys wusb54XX(forgot) it's a usb wireless G adapter.
laptop spec
dell inspiron P3 1GHz
xp home (updated)
512MB

anyway, thank you everybody for your concern. Thank You!

 :)Sorry it took me a day or two to get back to this issue, but here is what to do. :)

1. Right click on the linksys app. symbol in the system tray (bottom left hand corner) click exit (cant remember exact wording, but close the program).

2. Go Start> Control Panel> Classic View(On left panel)> Network Connections.

3. Once that is open would should see a conception called "Wireless Network Connection #" db click.

4. On the new box select the option "View Wireless Networks"

5. In the main box there should be some long lengthy error message saying basically Windows can not control the device. If this in not present skip to step 10.

6. On the left hand side db click "Change Advanced Settings"

7. Click the "Wireless Networks" tab

8. Check the check box net to the sentence "Use windows to ....................."

9. Click OK and then repeat steps 2-4

10. Now select the network that is yours and hit connect. PRESTO ::) (Note: You may need to add any necessary encryption code if one is set, the box will appear automatically.)

The failure to see the internet means that a gateway IP address has not been assigned (probably).  You can assign this manually.  In your case, 192.168.1.1 is probably correct.  You can also assign your primary DNS to the same address.

this few days i search thru almost all the linksys forum. found out other WRT54G user have alot of problem,
all have different idea about it,
some may heat problem, they attach a colling fan on the router n finally work fine.
some follow the linksys support guy said, edit the RTS, beacon interval.... and it's work.
some even said it's win xp problem , download the hot fix KB884020,


for me,
i disable the DHCP. download the hot fix, change the RTS,  beacon interval, fragmen...give up the xxxx linksys s/w use the WZC
make my both pc use static ip. and the result is sucess connect to router for 2day, never disconnect. but yesterday i cannot connect intrnet. so, seem there's no more option for me, i download the latest firmware from linksys,

my WRT54G is V4. so i download the firmware for in and install. ,, after install , i check my router setup page,  some how my router become WRT54GL i double check the firmware i download, it's correct version. so i hope it's ok.
