IT technical support - wireless networks - A bit of advice


Between wireless home networking is a virtual must become. Must you be with many houses which now hosting one or more computers and laptops able, to share your photos and other data. Recently, with the advent of online gaming and the development of the Xbox 360, PlayStation, Wii all so that your users compete against other remote players, wireless networks become a necessity rather than an option.

Broadband is now getting faster and faster, with most suppliers now provides wireless routers, it becomes easy, hinzuzufügen.Ich am simply saying all of your computers, game consoles and other devices, but this is not always so many of our customers find out the hard way.

We were asked to solve numerous wireless and network routers.Often we are able to resolve these issues with relative ease, after a simple change in the customer router Konfiguration.Viele of problems are caused by faulty hardware! We have opened new, branded equipment from his box to find it just doesn't work time to time.

Increasingly we find that have the hardware, most routers, errors in the software within the router gives a variety of questions, then by a future firmware software update distributed, visualizer.some brands seem resolved by the manufacturer to launch your new product price, only to update after update, resolving questions within the router to produzieren.Dies will cause that all Manor inconvenience to end users. Security problems, connection issues, questions of stability, nothing is sacred.

Considering its fact we no longer use all routers on the market and keep is consultation with our customers, has stood the test of time to the product, or sometimes just wait to stop the steady stream of updates/repairs!

Wireless adapter suffer another problem on the other hand. Electrocution! To suffer from this problem, but to be become stable in recent years seem also used USB memory sticks.When I say that electric shock, short circuit may have a phrase besser.Viele of customers advice to shut down to the USB port before separation hardware not followed, but very often are our engineers speak this before completely unaware.Our research we found that many wireless USB network adapter stop working disconnected after this way.Please be warned, the USB port always shut down or the entire machine shut down before you pull the network adapter.If you can not, but every time come get it once, maybe twice.This is for the Xbox 360 wireless adapter, make sure you disable before disconnecting the console.

After the damage has been done, seems to not work scheint.Mehr as often the USB network adapter often, is the PC nor recognize but not load the adapter and driver, see all Netzwerke.Andere times the adapter in the network can recognize, but is not in both directions to kommunizieren.Gelegentlich Windows will recognize easily again the device! sorry, it's not all, what can you do at this stage except return the network adapter to the shop and try to get a replacement or your money back.

Our advice for you as a consumer research of your wireless router reading is up, as much as you can search the forums for comments and questions with suffering from others and usually wait until at least 6 months after the product release to the public wurde.Als for the wireless network adapter,

TURN OFF THE POWER SUPPLY BEFORE THEY DISCONNECT!

Question about networking (layer 2) [static ip addresses] [ethernet packet]

Q: This is more a basic network involved. I just curious.

If, say, a switch and then a PC connected to one port (A) and another on a different port (B). They all have static IP address, say 192.168.0.1

From 0.2 and 0.1 PC I ping the machine is 0.2, the switch knows the MAC of 0.1 on port A, but how does PC know 0.1 what MAC address to set the “Destination Address” field in the ?
Best Answer: I don't know who told you only layer 1 devices can be touched, but that is just silly. What device exists that cannot be touched? There is no imagination layer in networking.

Switch/hub is usually layer 2, although some switches do some layer 3 functionality. router is layer 3 but many home routers contain a small switch (this is how they offer 4 or more LAN ports for example). So the line is not clear in every case in how to label a device. It is very clear however in how to label each function the device provides.

Server contain many parts, hardware and software. They contain a network card which functions on layer 1 and 2. They contain an IP stack which provides layer 3 and 4, and services and application software which provides layers 5-7 (things get murky in the upper layers, sometimes everything above layer 4 is called the "application layer" or "layer 7" and treated as a group.
Re:Ah ok, this makes a lot more sense now! I was looking for a command like that too.

Thanks everyone!
Re:Originally posted by: guy
So do each of the PCs keep a table of IPs to MAC address entries?

I understand how a switch knows how to forward to which port, just confused on how the PCs know which MAC address to put in for the DA MAC.
Yup, each host keeps an arp table/cache of the other hosts they can connect to over layer 2. If you're running a windows machine bring up a command prompt and type "arp -a" to see what your machine has in it's cache right now.

Re:So do each of the PCs keep a table of IPs to MAC address entries?

I understand how a switch knows how to forward to which port, just confused on how the PCs know which MAC address to put in for the DA MAC.
Re:A switch is essentially a fast, multi-port bridge, and it operates as a bridge does (@ Layer 2).

The bridge gets it's addresses (MACs) by passively listening and noting the *source* address of the frame on the "wire". If it hasn't seen that source before, it adds it to the forwarding table (for whatever the defined amount of time). It goes in the table as 'this MAC came in from this Port'.

When one device send a frame to another, the switch/bridge looks at the destination MAC … if it's in the table, it sends the frame out that port. It also looks at the source address … if that source is not in the table, it's added.

If the destination MAC is not in the table (unknown), the switch/bridge "Floods" the frame out all ports except the one it came in on.

Do not confuse "Flooding" with "Broadcasting" … they are different.

With a broadcast, the destination MAC is all ones (usually, by convention) which matches all addresses in the broadcast domain.

Flooding sends the frame out all ports with the source and destination address intact (not all ones destination). The general idea is that if the destination evice is out there, it'll get the frame and respond accordingly.

Hope this helps

Scott

Edit: Nuts. I somehow managed to miss the whole last paragraph of the OP … I gotta get some better drugs …
Re:Address Resolution Protocol. ARP.

It's a layer2 broadcast asking for "who has this IP address? Respond to my source mac address"
