Without actually having a 2701 in front of me (and I'm having a hard time finding an emulator) I can't say much about what's possibly wrong in the configuration. I'd speculate that you've probably got something ticked incorrectly with regards to the MAC filter settings. Usually, SOHO routers do MAC filtering in either whitelist mode or blacklist mode - ...

First off, I downvoted your question for being too generic. Consider investing more own research and coming back with specific questions. To get you started: You are better off creating a site-to-site VPN. All your clients at site 2 then can access your resources at site 1. Implementation largely depends on your VPN solution. If you worry about bandwidth, ...

You'll need to give your computer a static IP address on the same range as the DD-WRT router to be able to access it. This can be done on either the ethernet or WiFi interface. Once the static IP address has been set to an IP address in the same range ( should start with 192.168.1.2 and end with 192.168.1.254 ), you'll be able to point your computer to ...

What the heck? So how do you tell Ubuntu that it is TKIP (or TKIP+AES)? I'm about to go back to Windows just because of this shit!

I think I have figured out the issue. In the meantime I had also observed at times the devices attached to the second wireless router get internet access momentarily (probably whenever they were reattached after the router has been disconnected for sometime) but that was not consistent. This suggested there could be some issue with either the switch ...

First, you have to understand that routers are nothing more than embedded (ultra-compact) computers with specialized networking hardware. The firmware of a router consists of the operating system, drivers, and applications that the router runs. Because routers are embedded devices, these need to be as efficient and small as possible. This is why the ...

Firmware is specific to hardware and it's capabilities. This applies to routers, phones (not only smartphones), big routers, switches, bridges, you name it. There's certain part of firmware that does low-level tasks like reading from Flash/disk storage, the next part tells how to talk to radio or how to talk to an onboard LAN chip. In case of (A)DSL routers ...

A router's firmware does more than just handle networking protocols. It tells the device how to operate. It decides what to do when you turn the device on. It can provide a web, telnet, ssh, etc interface for users to manage it. It contains all the custom settings you set. It does a lot more than just handle networking protocols. Think of it as the ...

This setup would not work as DSL networks are designed to allow only one device to be connected over a single line at time to the ISP and two routers would simply "confuse" the system. You could 1)as previously suggested, run a cat5 ethernet cable between the 2 locations, granted that the cable length is less than 100m 2)Use inexpensive powerline ...

I had the exact same issue with Devolo HomePlugs. At times, they even caused the ASDL connection to drop completely. They seemed to be causing issues with the router directly. This actually seems to be a common issue with them. I since upgraded to TP-LINK's Which are working great with full speed connections and no issues yet. I'd honestly say give ...

Enabling Advanced DNS Service on D-Link routers causes it to route DNS requests through a service called OpenDNS. Unchecking it will instead use your ISPs DNS servers, or you can manually configure other DNS servers to use. It could be that there are/were some network path issues between your router and the OpenDNS servers your D-Link router was attempting ...

You're looking for iwlist. Ordinarily you would do something like iwlist wlan0 scan (Where wlan0 is the name of your wireless network interface.)

Well, I still haven't fixed it, but after flashing my router with DD-WRT firmware (TP-LINK Archer C7) I've got 2 reasonable workarounds. Connect using wireless, just for Internet access, and use the wired connection for the LAN. Using wireless 'n' I can get speeds up to 60Mbps. I've got an 'ac' router and adapter, but for some reason I can only get 30Mbps ...

You probably want to leave this field blank. I had the exact same question when using the dd-wrt.v24-18946_NEWD-2_K2.6_mega-nv60k firmware on my linksys e3000. For some odd reason using the same port forwarding settings I've used in previous dd-wrt builds did not result in appropriate port forwarding (i.e. nmap always showed my router's external port 80 as ...

Most if not all devices now comes with auto sense network ports in which the logic of the signal get negotiated between the devices, probably in any popular piece of equipment shipped in last decade you can ignore if a cross patch is needed. As wrong cable was the most common source of issues for soho users, and as now most hw is powerful enough, you can ...

If you are referring to the situation from back-in-the-day, with less ambiguous devices, and no auto-mdi(x) as a matter of academic inquiry, as it rarely matters today: In summary: Routers (which are hosts) and workstations(etc) require straight-thru cables to connect to switches. Host-to-host connections require cross-over cables, as do ...

Two reasons: Your DSL router probably has an integrated (usually 4 port) switch (those 4 lan ports on the back side) Most modern network cards support Auto MDI-X, so they can 'swap' the pin assignment (so you can use the "wrong" cable)

I am not sure how accurate this is re your "true" speed, but the way ISPs normally expect you to check your speed is going to http://www.speedtest.net/ and i'm sure it's not false! If your speed is poor then you can always call and ask them and quote the results that site gives you.

Your "true average internet speed" is actually between your computer and the places you connect to on the web. Just because your policy allows for a connection of that magnitude doesn't mean the places you are visiting on the web have infrastructure to communicate with your computer at your requested data rate. Very few people are going to just open up the ...

It's too soon to say with certainty, but I think I've resolved the issue. I replaced my Linksys EA-3500 with an ASUS RT-N66U and I haven't had any issues with losing files since. I will keep a close eye on it to see if I do lose files, and try to remember to update this post if that happens. My guess is that there is some issue with the firmware on the ...

What happens if you plug both powerline devices into the same plug strip AND turn off every circuit breaker in the house except the one powering this circuit? (i.e. Eliminate all possible sources of powerline noise.) If you find this resolves your speed issue then turn breakers back on one at a time until you find which has the noise source (and it may not ...

I think I found an answer to your question. It looks like 10.0.0.1/8 is known to make some routers unresponsive. Try doing a 30/30/30 reset and using 10.0.0.1/24 http://lists.pfsense.org/pipermail/list/2011-November/000813.html

Yes, that’s possible. Open the “Network and Sharing Center”, select “Change adapter settings” (on the left). In the view that comes up now, select both your wired and wireless connection, right-click on one of them and select “Bridge Connections”. A guide with pictures is also available here.

Most cable internet providers requires you to use the same MAC address used before. Here are few steps that you can try: Check if your WAN interface can negotiate DHCP configuration; Try to use your computer's network configuration on WAN interface (IP address, subnet mask, default gateway and DNS); Try to ping to internet IP address (e.g. default ...

OUCH. A router won't have just have one IP. I suggest 'networking first step' by wendell odom. You write "From my understanding the destination stays the same but the source will update as it goes through its path." It's not clear what you're talking about. You haven't written much and the little that you've written has been ambiguous. If you cannot ...

Assuming the routers are not doing NAT (Network Address Translation. The source and destination addresses will stay the same at each point on the network. If you only had one router in between the two hosts, the MAC addresses would remain the same. I would expect the same behavior in this case. The arp program will show you what mac address is expected. ...

Your example is flawed. (I saw you edit it, it's still flawed.) In your example, Router 1 and 2 are on the same subnet (i.e. they have the same subnet mask). So Computer 1 is NOT going to send anything out of the default gateway, it is simply going to throw the packet out of the NIC and expect that a switch or the medium will get it to Computer 2. Now, if ...

Whew. This is a bit of a tricky one given your scenario. First off, router 2 shouldn't share an interface with router 1 that is also on their client-side interfaces. In your example, all 4 devices share the same LAN segment, which as an aside is in the non-routable (edit: across the "Internet") IP address range for the 192.168.x.y family. A better way ...


0

You are half right, in that the MAC address changes with each hop, but the IP addresses of the connection do not change unless there is NAT/PAT technology inline, or an application proxy is in use. Note, I believe the address for computer2 should be somthing like 192.168.2.12, rather than 1.12. that would imply that your packet doesn't go through router2 ...

There should be 4 DNS IP addresses on your router, but in two different places. 2 that the router actually uses, and 2 that it passes out via DHCP (how you get an IP address from the router). The two DNS IP addresses for DHCP on your router are there so that it can pass those along to the clients that connect to the router and get a DHCP address. You can ...

Your settings are correct, but you might want to change the DNS on the computers to automaticaly obtain the DNS from the router. This can prevent the computer dropping out of the network some times. I had it my self, my pc deadlocking the internet because of a preset DNS. The one on the router you should not change, because this is given to you by your ISP. ...

I finally accepted the fact that the wireless access point built into my router should just be turned off. I have a similar situation, the modem and router are not in a prime location for wifi (today), yet the hard-wire portion of the network also terminates there. 7 years ago with just a 2.4 ghz network everything was fine. My solution was to buy a ...

I'm assuming your router connects to the modem via a CAT5 cable. If so just run CAT5 from Modem location to patch panel and cable into Router. I've done this in many installations and left the Fibre modem near the entry point and patched RJ45 into patch panel at the desired location. Alternately, you can also patch a ADSL line into a patch panel, you only ...

See the answers posted here. "In your case both source and destination IP address are in the same subnet, so the destination is directly reachable and the packet is thus delivered directly without router involvement. That's why you see only a single hop in the traceroute output."

The ISP replaced my router with new piece and now it works fine. I can only guess what the problem was, but at least the Wifi works now.

Maybe you can download the free "Network scanner" tool from Softperfect. It shows you a list of all connected devices and their IP addresses.Then attach the router only to you PC with an ethernet cable and type the IP into your browser. You should then arrive at the router's internal home page. Hope my answer can help you!

Quite simply you have connected everything up wrong. connect your modem to your router as follows: Modem -> ethernet cable -> router "WAN" socket Connect your PC to your router as follows PC (IC Plus 10/100/1000 adapter) -> ethernet cable -> router "1" socket You could, in theory, then connect other ethernet devices to router ports 2, 3 and ...

There are a number of open-source network simulators that meet your requirements. They all create and connect virtual machines to form a virtual network running on a host PC. Students can run open-source networking software, such as quagga, on each VM and use other open-source tools, such as Wireshark, to monitor activity in the virtual network. Some ...

Ethernet switches do not broadcast all traffic to all ports. A unicast exchange between two hosts on two separate switch ports will not be seen by a listening host on a third switch port under normal operating conditions. More expensive managed switches, with enterprise functions such as VLAN support often have port mirroring features, that serve as a ...

I highly suggest you change your router password to something long, 12-20 characters if possible. It's not exactly easy for you to see if someone is trying to get into your router so the longer the pass the longer it'll take to bruteforce. It's not the best solution but it is an okay one. Some routers have a password of the day login too which depending ...

> I have been using this for many years without any issues. That might be the actual culprit, electronics 'gets old' similar to how mechanics wear out (even for light usage) over time.

From OP's comment on the original question: After weeks of having this problem, I think the culprit was software that came with my motherboard... Intel IT Director. As soon as I uninstalled it, the problem has disapperead. I don't know how it was causing the problem, but I tried reinstalling it and the problem started happening again.

Probe your network to see what MAC addresses and IP's are being used. Check what kind of traffic is going across your network. What kind of services, such as DHCP, DNS, RIP, etc, are being serviced by each router that might be causing conflicts of confusion?

I'm not very familiar with Macintosh computers, but I am with Ethernet and TCP/IP networking. Other than using some kind of aggregation/link sharing/splitting scheme, the answer to your "why didn't it use the other link" question is.. it depends on what interface(s) the applications in question are bound to, if they can find another route, and so on.

You cannot do this with certainty due to the fact that you cannot control the initial/factory-default IP/subnet assigned to the new router until after you've set the router up. It's the "chicken vs the egg" problem. What you can do is unplug your main network and plug the new router in, configure the new router to a different IP and subnet as the first thing ...

I'll first refer you to this link. Basically speaking, if your device is a simultaneous dual-band router, the potential bandwidth could have been doubled. However, this is subject to other limitations: Compatibility. Your device may not work properly in 5GHz channel. 802.11 version. I'm not sure if both band will offer equal transmission rate. Say if the ...

If you want to route ALL traffic from your LAN through VPN, it is easier than routing selected network traffic. Be aware, that VPN is not VPN, means not all VPN clients can connect with all VPN servers. For example CiscoVPN is not compatible with OpenVPN. Depending on your VPN server, you need the VPN client. If you use OpenVPN server, you could use a ...
