Hello, For the past two years, my friend and I both played Xbox LIVE on two different Xbox 360s at his house with no problems whatsoever. We had both of our 360s hardwired directly to a linksys router...

It sounds to me like you have the possible router troubles well in hand. Good job on that!

This is a long shot - in the dark ... have you checked your cat five ethernet connections? I think you have a failed or failing cable. You could have the cables tested or you could simply purchase a new cable. Any computer repair shop should have the test equipment for this - or you could get your own equipment. If you are in North America, you can find this equipment for sale at Best Buy, Home Depot, Lowes, Radio Shack or other fine retail outlet catering to the do it your selfer. Expect to pay up to $75.00 for the device. You might also want to check the RJ-45 in the X-Box. (There are at least 2 kinds of cables - 'straight' and 'cross-over'. I believe you should be using straight cables)

TCP-IP means Transmission Control Protocol - Internet Protocol. The way it works is TCP-IP transmits a packet (of information) out to the cloud - if a proper return is received, TCP-IP sends the next packet. This happens over and over. If one packet is lost - TCP-IP sends that packet over again., and continues until a proper return is received. At the other end,when the packets emerge from the cloud, they are reassembled into the original message. A dirty or faulty contact can allow crashes of packets causing TCP-IP to transmit the packets again. When a lot of retransmitting of packets happens, that results in a sluggish connection.

I don't know this is your trouble ... I do hope you get your system working again. Best of luck to you and thanks for your question today. Other experts may have additional ideas for you to try.

Thanks again for visiting today.

Windows 7. cannot access router by typing into the web browser these numbers: get message that webpage cannot be found. router seems to be working because i can access the web as normal. ...


I got your issue, If you want to log into , make sure that the computer is online wired or wireless with your router, then try to open the page using If still its not opening the page then follow these steps,

1. Click on start--> Go to all Programs--> Accessories--> select command prompt

2. You will get a black window, which is the command prompt and you will find a small cursor blinking there you type in "ipconfig" (without cotes) and then hit enter.

3. Check what is the IP address/ IP v4 ipaddress , which must be in the range 192.168.0.x

4. Then in the next line type "ping" (without cotes) then it will give you reply 4 times and with the ping statistics Packets send=4, Received =4, lost =0.

5. Then type in the next line "start iexplore" then you will get Dlink router setup page opened.

Good Luck!

Thanks in advance!

I have a WRT54G Linksys Wireless Router and can not VPN or Remote to a server from behind it

It is a passthrough router. you can not create a tunnel using this router. Now if you are using any VPN software to connect to the network then you can try to open the ports on the router.
Reduce the MTU to 1365.
open the ports - 500 , 443-447, 1723, 10000-2000
Try this.
If your router is old then upgrade the firmware of the router.

NetGear WGR826V has no clear port forwarding section in the setup, the mamnual is as clear as brick as to how do I forward a port on this brain dead router?

Forwarding Port – If you select 'Same as Incoming port' then all incoming traffic on specified Service is forwarded to LAN server without modifying Destination Port. – If you select 'Forward to another port range' then all incoming traffic received on the Service port (or range of ports) is forwarded to this port or range of ports of the LAN Server. – This field is disabled if action selected is "Block Always". – If you want to forward the traffic to a single port then enter port value in start port and leave finish port empty. – If you want to forward the traffic to range of ports then enter non zero value in finish port and make sure that service record attached to this rule has range of ports and range is equal to that of forwarding ports. – For example if you select Service as HTTP (TCP/80), LAN Server IP address as and Forwarding port as 8080 then all traffic coming from internet on – TCP/80 (HTTP) to this Router is redirected to TCP/8080 port of • WAN Users: These settings determine which packets are covered by the firewall rule, based on their source (WAN) IP address. Select the desired option: – Any All IP addresses are covered by this firewall rule. – Address range If this option is selected, you must enter the "Start" and "Finish" fields. – Single address Enter the required address in the "Start" fields. • Log: This determines whether packets covered by this firewall rule are logged. Select the desired action. – Never - never log traffic considered by this firewall rule, whether it matches or not. – Match - Log traffic only it matches this firewall rule. (The action is determined by this firewall rule.)
Ok well this is out of the manual, to me it seems straight forwards, but it is a brick too though, there is an example to help you, basically you tell it the Address of the PC, (Right click on NIC and get address) that you want ports to go to.. then ALLOW it, UN-disable actually.. in the tables.

My downloads stop usually after a few seconds i seem to only have this problem with about 50% of sites that i try to download from. Sometimes it happens on youtube or some sites like rapidshare. I will...

Sounds like a MTU issue. The "MTU" also means "Maximum Transmission Unit". This has to do with the largest packet that you can send on a particular link. In the old days, routers would break a large packet into fragments when they were about to transmit a packet onto a link with a lower MTU.
But this slows down the router and your connection. So these days, windows sets the "Don't Fragment" flag - and rather than break the packet, the router will respond with an ICMP packet that tells your system to send smaller packets - and your system will send smaller packets and avoid the fragmentation load and slowdown.
Problem is that sometimes the ICMp responses do not get through. Security professionals used to block all ICMP, willy-nilly. ICMP (except perhaps Ping) should never be blocked. is a great discussion of this.
What happens is,
1. You open a connection to site X. You tell them that the largest packet you will take is 1500 because that is the MTU on your wireless net.
2. The packets that are used to open the connection are small packets. Then, when the data starts flowing, large packets are sent. One of the packets is too big. The router between them and you sends the "whoops, too big" packet, and they filter it at their end.
3. They resend the packet and it never gets through. You eventually give up.
The problem is on their end - but let me ask this:
If you connect to the modem via a wire, does it change anything? I honestly don't think it is your problem, but it could be - if this is not the issue.
To diagnose, use this scheme to set your MTU to 576.
and then see if you can access these sites. If you can access these sites now, then this is your problem.
I do not know anything about your topology, but if you happen to have a link to you with a reduced MTU (are you running PPPoE? Who is your supplier?) and you can figure out what that MTU is, then by setting the MTU on the wireless link to that number, you will avoid having these sites send you large packets. The ICMP response never gets there but it is never needed.
What I don't get is why a reload would EVER work. The response should either go through or not. Resending the same stream should cause a problem in the same place.
Here is an alternate theory:
Years ago, I had a problem downloading a particular file via DSL. Just one file...out of many hundreds I'd downloaded. And occasionally I had a problem with a bit of web content but who cares? But this was a file and it was a hard failure so I could look at it further.
I had my friend compress the file (which changes the pattern of data in the file), and got a copy of the compressed file. Then I blew up the file and looked in the file with a hex editor and, paid special attention to the hunk that was just past the part where the file had hung.
Well, the ping command on Linux allowed you to send a ping with not only a particular buffer length but a particular payload, and what I discovered was that when I sent a particular packet (that matched the part of the file that failed) I would never get the response.
I called my ISP and explained that I had a ping that would fail when certain data came through but not when other data came through and that I could ping with a packet of a certain length but when I sent a packet with different data and the same length I never got a response.
The only difference was the data part of the packet.
I ended up at the highest tech level and they started tracing things while I ran my ping - and suddenly my link went completely dark for a minute and then started working. They had replaced my link card - on my ADSL link. It was sensitive to the content of the data. The internal indication they got was that the checksum had failed so the packet was dropped, but the hardware was broken and they were miscalculating the checksum, the packet was actually fine when they looked at the dump. (As I recall, 64 bytes of hex 0f0f0f0f0f0f would fail so it was simple to see that what I sent got there, by inspection).
Now, there is a possibility that the link, either the wi-fi at your end or the DSL link hardware is broken and is broken in a way (like mine was) where it is data sensitive. And some data causes it to be likely to toss the packet on the floor, while other data makes it through just fine.
If I was a techie, I would get a copy of a program called Wireshark. This program used to be called ethereal, and it allows you to trace what goes over your IP connection and through your adapter. If you understand IP you might be able to see where the TCP connection stalls and then when you restart it and it goes through, what is in the packet following the stall. If it fails in the same way every time, it might be possible to use something like wget for windows (which see: like ) and to get a particular file and cause a reliable failure, or a high percentage of failures, and with that in hand to call your ISP.
If you can cause the problem to happen with multiple computers at your end you might be able to get them not to look at your computer.
A trace of a failing wget would be the next thing I would look for. Hope this helps, let us know what happens.
A final theory is that, to stop people from filesharing, the ISP is rolling your IP address every few minutes. By breaking a PPPoE connection and forcing the router to reconnect and always supplying a new IP address, or doing the same sort of thing with a short DHCP timeout and rolling the IP address, they could do a lot to interfere with the popular programs that share large files, like bittorrent and such.
If you happened to be downloading a file when your IP address changed, it would, perforce, cause your download to be interrupted...the ISP could stop sending packets with your old IP address instantly, and, in this case, control-r would have a good chance of working, since well designed web programs use cookies and magic URLs to identify the stream, and not origin IP since so many people mash a bunch of identities into different streams from one IP address.
You could diagnose this by connecting to your router and determining what your exterior IP address is, then, when you get a hang, see if the exterior IP address has changed.

Wi Fi fine, ISP fine, no internet via LAN connection though.

Make sure your firewall is not blocking your ability to go to websites. I saw this the other day, somehow the users firewall was set to block all internet traffic out of the computer.
