Thread:  LAN Reconnect
ANSWERED / UNRESOLVED

Forum member bhm22mc says they have sales associates coming in and out of the office, and plugging laptops into a Linksys G. For some reason  the mapped drives and printers don't come back automatically. Bhm22mc asks other forum members for details on reconnecting to the LAN. Forum members suggest using batch files and also point out an excellent online resource for using batch files to get tasks done quickly.

Hi All. I have salesman coming in and out of the office. When they power on their laptops they hook into the Linksys_g without a problem, but their mapped drives and printers don't come back automatically. They can double click the "disconnected network drive" and it re-connects but not the printer(s). I have to map the printers because our main app still uses LPT(*) mapping.

Any help appreciated,
Bill

You might consider a batch file with the "net use" command combinations.

Any good links for creating "batch files"? I'm new at that. Thanks for the reply.

Thread: (RON) Dropping browser connections
ANSWERED / UNRESOLVED

Forum member ronzz1 says they have WPA on their wireless network, but for whatever reason, the laptop has suddenly started dropping browser connections. This happens with several browsers, and even after a network card driver update. Several forum members are able to offer ronzz1 some suggestions as to why the browser connection can drop.

I have WPA security on my wireless network, and just a couple days ago, my laptop suddenly began dropping browser connections. I've tried IE, Firefox, and Opera. My laptop is a Toshiba Satellite. I downloaded the latest drivers for my network card, with no improvement. Any suggestions?

Run a Constant ping test from your cmd prompt (start -> run -> cmd -> ping *gateway IP address here* -t) to see if its the browser that's dropping or the actual internet connection.

Try moving your laptop closer to the router and see if the connection still drops. save your router settings to a .cfg file and update firmware (then re-apply the .cfg file so its the same). you will need to do this from a wired computer to the router.

If this is a Linksys router, it is possible to be too close, also. If so, you would probably want to be at least 5'-6' away. It sounds dumb, but it makes a difference.

A correct channel/antenna (combination) will yield a result that does not compromise distance coverage performance, if needed.

Thread:  Internal shares safe/separate from hotspot?
ANSWERED / UNRESOLVED

Forum member CruelSun wants to add public wireless access to a lobby area some distance away from a secured business wireless to provide Internet access and file sharing to his small business. While our forum members are able to offer the technical advice to do this, it comes with a very strong warning -  mixing a business LAN with public access is not generally advised as it introduces new security issues that need to be considered.

  
 CruelSun
I have a cable modem connected to a Linksys WRV200 to provide internet access and file sharing to my small business. The business wireless is secured. I would like to add public wireless access to a lobby area some distance away from the WRV200. Due to the construction/layout of the building, a separate WAP would have to be installed near the Lobby area.

How can I add public wireless without allowing access to my network shares or otherwise compromising the security of my business LAN?
 

  
 Greenstead
It is not really advisable to mix a business LAN with public access. Whilst it is possible to configure such setups for security you would always be at risk. Far better to install a separate internet service for your public users.
 
  
CruelSun
Agreed on all counts, but If I can avoid the additional monthly expense of a second cable modem, I can live with a reasonable amount of risk. How would you accomplish this task if it was not feasible to install a separate internet service?
 
  
 Greenstead
It is problematic to achieve at a low cost with a single ISP since it requires more equipment. You should not mix business wireless users with public wireless users connecting to the same WRV200.

As an example in the configuration below the existing WRV200 could be used to provide the 'business firewall -> business wired/wireless AP'. The 'gateway (router/switch)' could be a 2nd WRV200 with the 'public AP' a Linksys WRE54G WirelessG Range Expander .

ISP -> gateway (router/switch) -> business firewall -> business wired/wireless AP. ISP -> gateway (router/switch) -> public AP.
 

  
CruelSun
If I understand your example, I would install a new router (R#1) to the cable modem, then connect the existing WVR200(R#2) to one port of R#1, and a new (public) WAP to another port of R#1.

ISP -> Router1 -> Router2 ->(business Wired/Wireless LAN)
ISP -> Router1 -> WAP (Public hotspot)

  • Does this require any special configuration on R#1?
  • Does this require any change to the configuration of R#2?
  • I guess I should assign a static IP to the R#2 WAN side, as I will have to forward some ports from
    R#1->R#2->Server
  • Would it enhance security between the LAN segments to set each Router's Lan side IP scope differently (R#1=192.168.xxx.xxx, R#2=10.xxx.xxx.xxx)?

An Afterthought...
Would this example work as well, and keep the business LAN safe without the added complexity and latency of being two routers deep?

ISP -> Router1 -> (business Wired/Wireless Lan using 10.xxx.xxx.xxx)
ISP -> Router1 -> Router2 ->WAP (Public hotspot using 192.168.xxx.xxx)
