I now know that I would need a special USB cable or a cross-over ethernet cable for a wired connection. As I don't have either at the moment I looked into creating a ad-hoc WiFi network between both computers. I found instructions how to set one up under Win XP and another one for Win 7 but I have found no information whether and how I can actually connect both. I reckon that I only need to set one up on one computer and then would have to somehow make the other computer detect and join that network.
I have a Sony TV connected to my Wi-Fi and a MacBook Pro connected to my Wi-Fi. How do I make a network of these two pieces of equipment?

View 3 Replies View RelatedI need to get the internet from my uncle and aunt's house to my grandma's house next door. I don't know exact feet or anything like that yet but I will get it measured off. My grandma's kids got her a laptop for Christmas but she doesn't have the internet or would be wanting to spend money on it a month since she already says she will not be able to use the computer, but I said we would just somehow get the internet from next door. I don't know off the top of my head but my aunts computer is an older Dell, early P4 computer with xp on it. It's slow but it does work so that is the computer. The router is some sort of D-link with one antenna on it and I'm pretty sure it's probably a G-router(2.4ghz) and not a N-router, but can get that info later too! They currently use Time Warner Cable Roadrunner Turbo for their internet. Both places are well built brick houses and at least 200-300 feet apart. I checked yesterday and the computer was able to pick up the signal in my grandma's house on the end that was closest to my aunts house. It was showing 2 bars but it wasn't extremely fast and that room had a bigger window in it probably allowing some of the signal in? If you moved from that point of the house though and tried to go to the other end, the signal was lost. The router in my aunt's house is one room away from the end of the house that is closest to my grandma's so it could be moved closer but I don't think that will fix the signal enough to do what I need it to do.

View 5 Replies View RelatedI have a toshiba satellite laptop (windows 7) with wireless on-board and an ethernet cable port. Up until last night, both worked flawlessly since I bought the computer a few years ago.
Now, the wireless still works in three different locations I have tried (i.e. three different networks), but the ethernet cable will not work. I thought it was the ethernet connection on the mobo at first, but then after acquiring a USB-NIC connection, I found I had the exact same problem... I can't connect to my router or even direct to the DSL modem using a ethernet cable. I know my system is good since all my other computers (7) work with wired connections, and my laptop doesn't work on other cables on which other computers do. Essentially, it appears that my computer has lost the ability to get an i.p. address using an ethernet cable of any kind. Both the onboard card and the usb-nic cable tell me they are 'working correctly' in the systems/devices/network adapters section. I have tried disabling one while trying the other. I have tried disabling the wireless while trying either, and still nothing.
Trying to establish a wireless connection from WD TV Live Plus unit to Westell 327W router using an AirLink 150 adapter. The media player sees my network and seems to have a good signal, but keeps telling me "limited or no connectivity." The media player (with adapter) is about 20 feet from the router with direct line-of-sight.Also, 3 other Wi-Fi devices having no problem connecting anywhere in the house.Power down/power up, move adapter to alternate USB port, re-try connection multiple times.

It has wireless built-in; however, I don't want to use it. Is it possible to use this modem and leave the wireless off? Or does the wireless automatically turn-on whenever the modem is on? With all that said, is the built-in wireless any good? I recently purchased an ASUS RT-56 and would prefer using it to some built-in system.

View 1 Replies View RelatedI'm currently in the market for a new router that supports remote IPSec VPN access to my home network. The router must support wireless (latest "n" standard is a plus) and must have gigabit links for LAN at least. I have been considering the following two routers but neither has an IPSec VPN server built in to the router OS:
ASUS RT-N66U
MikroTik RB2011UAS-2HnD-IN
As far as I can tell they both have PPTP server functionality and only IPSec pass-through. I would like a router that has the server ability built in to the OS so I won't have to run an additional system behind my network edge. I can also look into any small to medium size business routers, just as long as it supports a majority of the same features of the two routers I have listed for comparison.
i have 2 no of 3560G in our core, now my requirement is to establish the redunent network like for the edge 2960G using stack or some other way ...

When I detached it the internet access to the desktop machine was not functioning. That was diagnosed as a problem with the I.P. address (presumably when i attached my laptop.) It was fixed over the phone through a START>RUN>CMd>config process. Now I find that my laptop won't connect to my NetGear home link (also cable) and wonder if the same problem might be happening, that connecting the laptop to the work network has scrambled it's recognition of the server or the I.P. address.I tried updating Kaspersky 2011 databases but it just keeps saying 'source not found'Another laptop using the same router connects perfectly each time.

Is there a way to change a 20 port to a 1.1 port, to establish a internet, DIALUP, connection with a Trendnet Model# TFM-561U fax modem? This computer is a new gateway 64Bit with windows 7 running IE9,(Gateway model# NV57H77u, 3GB DDR, 320GB HDD, all usb ports are 2.0, and wont recognise the modem for dialup. When I connected modem to my computer, 1.1 port, the dialup connection worked fine(but this computer is a 32BIT compac CQ-50 wm139 with widows 7 installed as upgrade running IE9, 2GB) I tryed to connect the compaq 2.0 port for connection and couldnt connect, the 2.0 ports recognise the device as a FAX unit and wont connect to the dialup it just gives me the dial sound and loud screech when num. is reached. I believe it has to be a 1.1 port to establish a connection because of the rate of transfer differance, between these two ports, dialup very slow.
View 6 Replies View RelatedI want to establish VPN with GRE over IPsec. As ASA can't end GRE tunnels, I should pass it through inside to another 1841 router in datacentar network. Since datacentar is connected to internet via two wan links (separate ISPs) is it possible to establish two gre simultanous sessions between 1841 at branch office and 1841 at datacentar, one session per wan link at datacentar? That way, I need 8 gre separate sessions (tunnels) at datacentar 1841 router. Is it supported?Is GRE passthrough works like regular port forwarding or it is something that ASA handles with some special commands?

Once again the sun sinks into its nightly reprieve; for the third time since I first set out on this mission. Before me, only the piercing glows of monitors that sting my eyes. Yet, I cannot look away. The clacking of keys, once triumphant battle drums of purpose, has grown sharp. They pierce my ears and my mind. It would be madness to continue. My body is weak. My resolve is waning. My sanity ...... tenuous. But if seeing this through means madness.....bring on the madness.
I'm trying to find a way to network my desktop (wired) and my laptop (wifi) so that I can swap files between the two easily. I've mostly been attempting this through Windows Homegroup, although I've also downloaded and installed TeamViewer. The thing is, the two just will not connect. After much poking around I found the specific symptom to be that wired connections and wireless connections refuse to speak. My laptop sees my roomie's laptop easily enough, though. And if I hardline my laptop to the router suddenly their best friends! - joining each others' Homegroup, swapping files, trading recipes!
Points of interest: I've noticed that, while both are enabled, only IPv4 connectivity indicates internet access; IPv6 says No Internet Access. Pings from one machine to the other result in "Request timed out" or "Destination Host Unreachable." I've disabled firewalls - Windows and the one on the router. Disabled and then uninstalled anti-virus. I've updated the router firmware and net adapter drivers I tried restoring router to factory settings, in case I changed something I shouldn't have along the way. I've alternated static and dynamic ip addresses - no difference there. I've just spotted a couple of errors in the Event Viewer that look like they could be leads;(!)ErrorDhcp-Client The IP address lease 192.168.2.2 for the Network Card with network address 0x6CF049E337F0 has been denied by the DHCP server 192.168.2.1 (The DHCP Server sent a DHCPNACK message).

2 days ago I bought Verbatim 2TB NAS with Gbs ethernet and connected it to Cisco Catalyst 2970 Gigabit switch. When I log in to cisco CP, monitoring tools shows that connection with NAS is 1000 Mbps, but file transfer speed is only 9-11 MBs per second (screen 1 and 2). This means that connection is 100Mbs, right?
So, how can I fix this, what is the problem with this NAS. I formated it from ext2 to ext3, nothing has changed, then restored it.
