• Windows XP ad-hoc networking

  - by Abhinav

  I have been using a Windows XP ad-hoc wireless network to connect my Macbook to the internet. Everything was working fine until after a restart of the XP machine, the network stopped appearing in the "Choose a wireless network" screen. It does not show up as an available network on the Macbook as well. But when I try to create a new network it shows me the network name. Creating a new network does not work either.

• CSMA/CD and CSMA/CA

  - by Zia ur Rahman

  CSMA/CD is used in wired LANs, CSMA means that the computers on the network sense the medium if the medium is idle, the computer transmits otherwise it defers sending.CD refers to collision detection. I don’t want to write about CD because its not related to my Question. Now in case of wireless LANs we use CSMA/CA , here CSMA refers to carrier sensing , the Question is how carrier sensing is done in case of wireless LANs? the collision avoidance is done by sending the control message to the intended receipient.

• Non-Airport Express wirless N router with audio server

  - by iansinke

  I'm interested in hooking up three things to a wireless router: speakers, a printer, and a hard disk. At first the obvious solution was Airport Express, but then I found out that Airport Express does not support hard disks. Any ideas as to other wireless routers that would have the requisite feature set?

• Is it possible to turn the DSL router/modem into a simple modem?

  - by Jader Dias

  I use a DSL router/modem + a wireless router. If the wireless router spoke PPoE could I suppress the router function of the DSL modem? I want to do that because I think it will reduce a routing hop improving performance and availability.

• Capturing wirelss traffic (using Wireshark).

  - by Daisetsu

  When I run wireshark on a wired network it works fine and reports all of the packets. When I run it on a wireless network though I only see my own traffic. The wireless card I have is supposed to support packet capture and go into premiscous mode, but I don't see any other system traffic. What is wrong?

• Creating a network link between 2 very close buildings

  - by Daniel Johnson

  I have a charity who have two adjacent medium sized modern detached houses (in the UK): the buildings stand next to each other and are less than 5 metres apart. They have DSL connected to a single computer in one of the buildings. They want to add a network with wireless, and want it to work across both buildings. Being a charity they need to keep costs down. The network would be used for sharing Word documents, e-mail, browsing and skyping. My initial thoughts were to connect the buildings with fibre. So: Option 1 Use fibre between the buildings. Sufficient cable and two TP-LINK MC100CM Fast Ethernet Media Converters. Cost ~£80.00. But there is the extra cost and hassle of running the cable down and up the external walls, lifting and relaying paving, and burying underground. Never having fitted fibre I'm also a little worried about going up the wall and then bending the cable at 90 degrees to go through the wall and into the building. Option 2 Use two TP-Link TL-WA7510N High Powered Outdoor 5Ghz 15dBi Wireless antennas to connect the buildings. There is a clear line of sight at first floor level. Cost ~£100. And much easier to fit than fibre! Is using the TL-WA7510Ns overkill? Is there something more suitable? I had hoped to use some Netgear stuff, e.g. two DGN2200, one in each house and also use them to provide the wireless link between the buildings. However, in bridge mode wireless client association is not available and repeater mode with client association only supports WEP security which isn't strong enough. Is there something similar that would be up to the job? Option 3 Connect the buildings with UTP cable. My concerns here are risk of electric shock due to a difference of potential between the buildings (or are they so close this shouldn't be an issue) and protection from lightning strikes. Is fitting lighting arrestors expensive? And what can be done to ameliorate against the risk of shock? This all falls outside my area of expertise so I would really appreciate some advice.

• Speed Problem with Wireless Connectivity on Cisco 877w

  - by Carl Crawley

  Having a bit of a weird one with my local LAN setup. I recently installed a Cisco 877W router on my DSL2+ connection and all is working really well.. Upgraded the IOS to 12.4 and my wired clients are streaming connectivity superfast at 1.3mb/s. However, there seems to be an issue with my wireless clients - I can't seem to stream any data across the local wireless connection (LAN) and using the Internet, whilst responsive enough isn't really comparable with the wired connection speed. For example, all devices are connected to an 8 Port Gb switch on FE0 from the Router with a NAS disk and on my wired clients, I can transfer/stream etc absolutely fine - however, transferring a local 700Mb file on my local LAN estimates 7-8 hours to transfer :( The Wireless config is as follows : interface Dot11Radio0 description WIRELESS INTERFACE no ip address ! encryption mode ciphers tkip ! ssid [MySSID] ! speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 channel 2462 station-role root rts threshold 2312 world-mode dot11d country GB indoor bridge-group 1 bridge-group 1 subscriber-loop-control bridge-group 1 spanning-disabled bridge-group 1 block-unknown-source no bridge-group 1 source-learning no bridge-group 1 unicast-flooding All devices are connected to the Gb Switch which is connected to FE0 with the following: Hardware is Fast Ethernet, address is 0021.a03e.6519 (bia 0021.a03e.6519) Description: Uplink to Switch MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output never, output hang never Last clearing of "show interface" counters never Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 14000 bits/sec, 19 packets/sec 5 minute output rate 167000 bits/sec, 23 packets/sec 177365 packets input, 52089562 bytes, 0 no buffer Received 919 broadcasts, 0 runts, 0 giants, 0 throttles 260 input errors, 260 CRC, 0 frame, 0 overrun, 0 ignored 0 input packets with dribble condition detected 156673 packets output, 106218222 bytes, 0 underruns 0 output errors, 0 collisions, 2 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out Not sure why I'm having problems on the wireless and I've reached the end of my Cisco knowledge...

• outlook security alert after adding a second wireless access point to the network

  - by Mark

  Just added a Netgear WG103 Wireless Access Point in our conference room to allow visitors to access the internet through out internal network. When switched on visitors can connect to the intenet and everything works fine. Except, when the Access Point is switched on, normal users of the network get a Security Alert when they try to start Outlook 2007. The Security Alert is the same as the one shown in question 148526 asked by desiny back in June 2010 (http://serverfault.com/questions/148526/outlook-security-alert-following-exchange-2007-upgrade-to-sp2) rather than "autodiscover.ad.unc.edu" my security alert references our "Remote.server.org.uk". If I view the certificate it relates to "Netgear HTTPS:....", but the only Netgear equipment we have is the new Access Point installed in the conference room. If the Access Point is not switched on we do not get the Security Alert. At first I thought it was because we had selected "WPA-PSK & WPA2-PSK" Network Authentication Type but it continues to occur even if we opt for "Shared Key" WEP Data Encryption. I do not understand why adding a Netgear Wireless Access point would cause Outlook to issue a Security Alert when users try to read their email. Does anyone know what I have to do to get rid of the Security Alert? Thanks in advance for reading this and helping me out.

• unable to access Internet by wireless but can by cable

  - by Jeff King

  i'M GOING MAD! UNtil last friday I had been successfully using wifi with the supplier as VIRGIN through their Motorola SB 4200 cable Modem and the wireless router being the Linksys WRT 54G router. Supported were three lap tops and an EPSON 510W printer and this had been running with no issue for about 3 years. Back to last friday, we started suffering significant delays and then the network collapsed with no wireless access. I was able to connect a single laptop direct to the cable modem and internet access was restored to just that one device. I thought that the problem was the router so I tried a backup D-Link device with no success. I have subsequently bought another cable modem AND a netgear router plus addidtional ethernet cables but with no success. The best that happens is that the signal appears good but I cannot get access to the internet. A yellow question mark appears on the 'gradient' icon. Each laptop and router works elsewhere so I'm stumped. Mind you I am a real novice so I'm not surprised. Please can anyone tell me what I'm doing wrong?
