View 1 RepliesI have a RV120W Firewall and I've created 3 Vlans. One for Internet Access Computers, One for non-Internet access, one for printers. How can I implement security to keep Internet and non-internet vlan computers from communicating with one anothers? Both computer vlans will need to communicate with printer
View 1 Replies View RelatedEverything in my network works as a charm. Every host in my vlans can access and ping the internet with no problems. But, my main router does not ping the internet (Pinging either ip "173.194.71.104" or domain "www.google.com" do not work). I don't know how is that possible since my hosts can ping the internet. Below is my main router confiurations

I want to connect to the Internet small office where docsis (internet over tv cable) is used as WAN.For similar tasks but other WANs (adsl, dial-up) I used 800 series. But now I can't find anything in this series to solve my issue. There is 815 but it has no wi-fi.
I can use cable modem that my ISP gave to me: this modem acts as bridge so I can use router with FE-based WAN but it is better to have one device instead of two.
I have a laptop that I take to work, and would like to set things up to use my home internet connection from elsewhere. I don't have another computer to function as a server for me at home, so would like to do it so that my router alone provides this access (log into it from the internet anywhere and use my internet as if I am using it from home). How would I go about doing this? Would it require installing new firmware?
View 1 Replies View RelatedI have a Sony Vaio running Windows 7 Home Premium. Yesterday I accessed the Internet at the office over a Cat5 cable. Last night I accessed the Internet at home via my USB Internet dongle (actually an O2 mobile phone). Today neither works. I have also tried to connect to the Internet via Wireless and that does not work either.Needless to say my desktop (using the same Cat5 cable) works. My mobile phone can access the Internet on it own. And others can get the wireless to work.My Vaio can connect to all three; however, all three say "No Internet access".I changed nothing between last night and this morning. I have scanned through the list of Windows Updates and nothing has been downloaded in the past week. I have turned off my firewalls (in both McAfee and Symantec Endpoint Protection). I have run the three NETSH reset commands with Administrator privileges. I have rebooted my machine numerous times. Nothing works.

View 6 Replies View RelatedI have a desktop computer that I have used for years and it has always worked just fine. We have AT&T (DSL, not cable) and it used to connect just fine but then I moved out, left everything plugged in exactly as it was and when I came back it wouldn't connect.It connects to the LAN but not to the internet. When I go in cmd to type ipconfig the DNS suffix is blank on that computer but says gateway.2wire.net on my wireless laptop. I eventually disabled UPnP on it because that's what alot of people were saying fixed the problem but it didn't fix anything. All it did was make the Internet Gateway Connection box disappear.Originally it was plugged in like so: Cable from wall > Cable Box > PC Now it is hooked up like this: Data cable from wall > DSL > Router > PC It stopped working BEFORE it was switched to DSL so that isn't the problem The DSL we have is "AT&T 2701HG-B 2Wire Wireless Gateway DSL Router Modem" and the Router it is plugged into that goes to my PC is a Linksys Wireless Router Model WRT54GS The PC is Windows XP Home, SP2?

View 3 Replies View RelatedI come here today with a problem that has been plaguing this laptop forever and a day. You see, about two or so years ago on this very laptop, it was just another day where I booted up my laptop and was going to get a good day of wasting time on the internet underway. I tried to open Firefox, and I got prompted to download an apparent update for the browser. Obviously I went along with it because it seemed pretty routine and identical to how Firefox had updated in the past.
After the update was all done and dusted, I found myself unable to connect to the internet through Firefox. I would just get a constant stream of "Unable to connect" messages. I thought it might have been a problem on my end since back then I had rather wishy washy internet. So I let it settle for a while. Later on that day I talked to a few of my buddies over Xbox Live and asked if they'd had any similar issues with the new Firefox update because at the time, we all used it and hadn't quite jumped ship to Chrome just yet. But no matter who I asked, I always got the same response "I didn't get any update." Which as you can imagine, confused me quite thoroughly.
My computer it connected to the internet wirelessly but i cant broswe the web or play video games online. I am an avid world of warcraft player but it tells me i cannot connect to the launcher. The laptops that connect to the same internet work just fine though. I have tried to connect through an ethernet cord with no luck.

View 1 Replies View RelatedI am experiencing random disconnects from the internet -- they have been occurring about 1-3 times per day, although I've just had four in the last 20 minutes.
ISP: Wow! Cable - 15/1Mbps
Modem: Motorola SB6121 (new)
Router: D-Link DIR-655 (new) Firmware 2.00NA
When the internet disconnects:
- Both the LAN & the WAN are affected, but I do not lose any wireless connectivity with the router itself.
- I am able to log into the router wirelessly but cannot access the modem.
- If I plug my laptop directly into the modem, I can connect to the internet.
- When I reboot (using the on/off switch on the surge protector), everything comes back up.
There are a couple of other wireless routers nearby with fairly strong signals, but they appear to be running on different channels.
My phones are DECT 6.0, so there shouldn't be any interference problems with those.
I've been poking around this forum, and have already made some setting changes that seem to be consistently recommended:
- Ensured DNS IP addresses are being filled in under Setup/Internet/Manual
- Turned off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
- Turned off Advanced DNS Services
- Turned on DNS Relay under Setup/Networking.
- Setup DHCP reserved IP addresses for all devices on the router.
- Ensured devices are set to auto obtain an IP address.
- Set Firewall settings to Endpoint Independent for TCP and UDP.
- Using mixed G and N signal mode
- My security setting is WPA-Personal. WPA2-PSK
I thought that the best option to do that in my Cisco 861 router, IOS v. 15.0 is to used NVI (Nat Virtual Interface)[url]...
I tried the solution given in this page, but is does not work.
I give you the running-config for my router before and after the modifications proposed in this page
