Linksys WUSB54AG keeps dropping wireless connection in linux
I'm using a Linksys WUSB54AG usb wireless interface with a D-Link DSL2640B router. My OS is Ubuntu 8.10, Intrepid Ibex, kernel is 2.6.27-11-generic. The Linksys WUSB54AG uses the Prism54 chipset which is supported in Linux. The driver for the Prism54 is p54.
lsusb output:
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 003: ID 13b1:000c Linksys Bus 001 Device 002: ID 054c:0243 Sony Corp. MicroVault Flash Drive Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Notice that the first line of my dmesg excerpt says ''firmware: requesting isl3887usb_bare''. Checking with the Linux Wireless site (http://wireless.kernel.org/) the file isl3887usb_bare is the correct firmware for my kernel. Why does dmesg report that the kernel was ''requesting isl3887usb_bare''? Did it find and load it? Note also that 2 lines down dmesg reports: ''p54: LM86 firmware''.
Is it using the right firmware? If not, how do I make it use the right firmware - I can download the firmware file isl3887usb_bare from the wireless Linux site. If the issue is not be related to the firmware - any ideas as to what it might be?
Several solutions for this problem.
-You can try to reposition the router in the room
- In the router set, change the channel from 6 to 7 or from 11 to 10
- Purchase a 9db-15db Wi-Fi signal booster antenna
- download the software from TP-Link
- download firmware upgrade from linksys
- download software http://www.download32.com/wireless-network-speed-booster-software.html

If it is not a router problem then you could try a wireless adaptor such as the Lapton N300 USB Adapter. This adapter will connect to all OS including Linux. $20 Max. I had a problem at home where a laptop would not connect at all and this adapter did the job. Maybe worth a try
Unfortunately, you can't use two routers together in that manner. You must have a device in between them such as a switch or bridge or you'll have to disable the DHCP server settings in the second router. The second router then pretty much becomes a switch you may then use all the ports on the second router with the exception of the WAN port it must remain unoccupied. However, if you need wireless connectivity in another location far away from your main router then your only solution would be to indeed purchase an actual access point/bridge device
It's always difficult to troubleshoot wireless because the signal can be effected by so many different variables. Easiest thing would be to connect another wireless device. If that works OK then it's your computer or wireless adapter. If that drops out too then it's your wireless router. When we find out what's at fault we can find a more detailed solution if you' be kind enough to post back.
Wireless internet is basically a radio, and radio signals can be interfered with. Simply running a microwave can make your signal go out. Many wireless phones run on the same frequency as your computer, which can mess it up. In any case, wired is always better than wireless.
First unplug your router, then unplug your modem and for 10 seconds. Next plug the modem back in and wait it to reboot(on mine this a series of 4 lights that light up in sequence, when the 4th light stops flashing, reboot is complete). Finally plug your router back in.
The first thing I would try is checking the firmware on the router. You can do this by interfacing with the router from a hardwired computer. The router should have a link on its interface (through your internet browser ex. internet explorer) asking to check for a firmware update. Run the utility from the router. Once it is complete, check to see if you can surf the net. I suggest using www.foxnews.com or www.bbc.com so you are sure you are pulling up a fresh page as they are dated. Also you can check the following link for information reguarding the firmware avalible for your router:
If you are not sure how to interface with your router, update the question and I can give you step by step instructions.
If you do perform a firmware update and the system keeps bumping when you try to connect wirelessly, check for other networks that show up on your laptop. If you see a lot, interface with your router and change the frequency to something on the high end or the low end. If it continues, then there is possibility that the radio in the router is malfunctioning and you will have to replace the router. Now my personal disclaimer: anytime you flash the firmware on anything you run the risk of killing the system perminately. Although it is VERY rare since the companies have done a good job making these fairly fail safe, it does happen. In my 8 years of experience I have never had this happen to me when updating a router, however there is a possibility.
This link indicates there may be an issue with hiding the SSID in the wireless router. A security item employed by some users. IF this is the case consider broadcasting the SSID and employing WEP or WPA encryption in the wireless configuration for both the router and the adapter cards to secure the wireless connections..
