Buffalo Air Station WHR-G300N Default IP

Feb 28, 2012

I have the Air Station WHR-G300N. I just moved here from CA, I was on Verizon and now trying to use it on my girlfriend Cox system I can't get it to operate correctly.

Her PC system stopped having internet connection after about 2 weeks(running on the router) and going with Cox's reboot procedure of eliminating the router it can back up and seems to work fine as soon as I hook it back to the modem it stops.

I have unplugged all cables waited 30 seconds on both systems a couple of times. The lights are on the modem and the router.

Routers / Switches :: Primary DNS Server Is Not Responding?

Jun 19, 2012

I got an internet from provider (which is LAN cable sticking from the wall) - and it works fine when I connect via LAN cable - when I write the IP Address, Subnet Mask, Default Gateway, and DNS servers on the LAN adapter and create a PPPoE connection with username and password. I want to do the same but wirelessly. I have an ASUS RT-N10 LX wi-fi router - and connected the cable from the provider to the WAN slot on the router. Then I have accessed the router from my laptop [URL] - and configured everything as it was on my laptop.

IP Adddress: 192.168.17.191
Submask: 255.255.252.0
Default Gateway: 192.168.16.1
DNS1: 192.168.1.250
DNS1: 192.168.1.10

Wireless network works fine, the default gateway is pinging - but DNS servers are not accessible. As a result no internet connection available ( Moreover - when I want to ping the DNS (ping 192.168.1.250) - I tries to get a response from other location 192.168.1.3

Routers / Switches :: Stand-Alone Router Network Not Responding?

Apr 11, 2011

I have this LinkSys by Cisco Wireless-N gigabit model# WRT310N router that quit functioning in a weird way. (it has Wi-Fi protected setup on it, not sure if that would effect it, it's disabled) I have a friend in the condo above mine, but i have a Dial-Up internet conn and can afford a good broadband internet conn. a co-worker gave this router to me, saying he didn't need it for his network at home. It was still in original box, unopened, So it was intact. i set it up so i can play Age of Empires 1 (you probably haven't heard of it, it's a single player or Multi-player TCP/IP comp-to-comp game from '96) and i used a gigabit wired conn, he used wireless-N laptop. We played a few games, on the 4th game, it locks up about 12 mins into the game. we try again, the comp not even recognize each other. Knowing a little about networking from watching the IT guys at work, i tried the PING command in cmd.exe in vista, it will ping the router, not the other laptop. same thing on the other laptop pinging my desktop. i unplugged the router, and went to sleep.Next day, i got back from work, called the friend, plugged the router back in, and it work for another 14 mins, no ping. possibilities? the LinkSys website doesn't give answers, so what is it?Further Edit: my Gigabit conn is going through a 3 ft CAT5e cable, and the wireless-N trans rate is set to 130 Mbps.

Buffalo WZR-HP-G300NH - Changed Routers Getting Kicked Off Multiple Times

Sep 24, 2011

I switched from a DLink DIR-655 to a Buffalo WZR-HP-G300NH recently and have been having problems keeping a wireless client bridge connected. The bridge in question is a Linksys WGA600N, and though it has been as solid as a rock with the DLink I find myself resetting it often to reconnect the device to my network under the Buffalo. The bridge has been flashed and reflashed to its latest FW and the router has been flashed with different versions of DD-WRT (Buffalo's versions and vanilla DD-WRT versions; currently on vanilla DD-WRT v24-sp2 build 14896), yet I'm still experiencing the same problem. Fuddling around with the some of the wireless settings like the wireless channels on the router seems to keep the bridge connected a little longer than usual, however once it disconnects the frequency of drops goes up again. Other wireless clients on my network don't seem to have this problem with exception to another bridge (WHR-HP-GN) that I returned due to becoming catatonic to both wired and wireless connections.

D-Link DIR-655 :: Possible To Set Up As Wireless Base Station For Any Router

May 20, 2011

I was wondering if it is at all possible to set up a DIR-655 as a wireless base station for any router (specifically a netgear wrg614 v10). I've read that the DIR-655 can be set up as an access point, but with my current situation it's not currently possible.If this is not compatible with this specific netgear router, is there any other solution besides having to purchase a dedicated access point?

Cisco Switches :: SG300-28P W / PoE Stops Responding?

Mar 21, 2013

I'm facing a peculiar problem while accessing the switch (regardless of the mode - L2 / L3) once I connect a WiFi router provided by the ISP (Local make). The Switch stops responding on the web based console as well as ping. The network remains up but hosts' stop responding to ping packets to each other too. Only way I get control of the switch again is by rebooting it.
 
Switch is operating at its default IP: 192.168.1.254 and the plugged in router has a hard coded IP of - 192.168.1.1. I've taken a cable from the router (from its Ethernet port) and I've plugged it in to the router.
 
Just for the sake of it I've plugged the router cable in the link ports too but the switch stop's responding.

Cisco Switches :: SG200-08 Web Interface Stops Responding

Aug 26, 2012

I bought a pair of SG200-08 switches a month ago and noticed that after a couple of weeks (give or take) the web interface stops responding (today being the 2nd time this happened). I am on v1.0.5.1 of the firmware on both switches. I can ping the switches just fine. I've run a port scan against then showing that port 80 is open. When I browse to either switch using IE9.0 or Chrome (v21) both show page loading however it remains blank - eventually the browser times out. I've tried multiple machines (just in case of port blocking) however always the same result.
 
To correct this I power cycle the switches and the web interface starts working.On the switching side, both seem to be working as there doesn't isn't any network impact (from what I can tell) however not being able to access the web interface is very irritating, not to mention making me wonder what else isn't working.

Cisco Firewall :: Ubuntu 10.04 / Firewall Starts Randomly Responding To ARP Requests For Other IPs

Aug 22, 2011

I have my firewall on IP 192.168.0.1 (for example, real IP is a class C address).  I have a web server (Ubuntu 10.04, though this happened before with an 8.04 box as well) on ip 192.168.0.101.  Everything will be functioning fine, and I won't have any issues for a while.  Then, randomly I'll have problems getting to my web server, getting disconnected from SSH sessions.  I go to one of my linux boxes and do an "arping -b 192.168.0.101" and I will get  two responses, one from my firewall and one from the box, as illustrated below.  The only way to correct the issue that I've run into is to reload the firewall, which will then behave properly again until it randomly decides to start answering ARP requests on the other IP again.

Cisco Switching/Routing :: 3750x Switches / 32 Loop Back Responding As A Broadcast?

Jun 7, 2012

I have a bunch of 3750x switches that each have a 10 gig routed link back to a central 4507 (loopback = 172.30.255.255).We carved up a /24 (of course, the /24 doesn't really exist except in our address tracking spreadsheet) into a bunch of /30's for routed WAN links and /32's for loopback addresses.We started on the low end for /30 subnets (ie 172.30.255.0/30, 172.30.255.4/30, etc.).We started at the high end for the /32 loopbacks (ie 172.30.255.255/32, 172.30.255.254/32, etc.)
 
Well, when I try pinging 172.30.255.255 from the access layer 3750x switches, the 3750x seems to be treating it as a broadcast ping where it lists each member that responds instead of the regular !!!!! response (this makes think something is odd with the 3750x).  Of course, only one member responds (the core).  But even the core seems to respond with the other end of the /30 instead of the actual /32 loopback (which makes me think something is odd in the core).  I could have sworn that I've setup similar topologies without problems (ie, using 10.0.0.0/32, 10.255.255.255/32, etc as loopbacks) and as long as the mask is a /32, it should work.Also, I can ping/ssh to that loopback if my laptop is on a directly connected subnet.  But I can't do it from any of the 3750x switches (which are also directly connected).I've double checked for overlapping subnets, but nope.  I don't see any.  Routing looks fine.  The actual /32 is being propagated everywhere properly.

D-Link DIR-825 :: Mozilla Firefox Not Responding

I've never had a router or network in my place and I've just bought a DIR-825. I previously had a DIR-615? but returned it because I was having this problem. Now I'm still having it with the 825.When I use IE or Mozilla Firefox(preferred) I can usually navigate 2-3 pages before the program stalls and goes (Not Responding) for about 15-20 seconds before it starts going again. Then it repeats again in about another 3-4 pages or so.

D-Link DIR-615 :: Router Itself Responding To Different TCP Stealth Scans

Oct 17, 2011

I decided to buy myself a DIR-615 Wireless N 300 Router, its wireless performance is thus far very stable and strong. This router factory firmware loaded is 5.10 HW: E3.I never use Router features like SPI and DoS Protection, and I always use DMZ for unrestricted filtering, I use a software firewall for protection and monitoring traversing packets.

The problem is, D-Link does limited filtering over DMZ, I�m not use to seeing this with other popular router brands, I�m not happy with this implementation of DMZ. Now what�s worse, the Router (not the computer set on DMZ) itself is responding to different TCP stealth scans like TCP NULL, XMAS, FIN.How to correct this without enabling protections like SPI, so the Router won�t respond nor drop these types of packets when a computer is set on DMZ.

D-Link DIR-615 :: Software Failure - Only 5 LED Lights Responding

Jan 29, 2012

I bought a new DIR-615 and tried to install dd-wrt on it. During the installation all of a sudden the router stopped blinking the led lights and stopped responding to anything. It's current status is that I can only see globe LED and the other 4 LAN LEDs in continuous green and NOT blinking. The power LED and wireless LED are not even displaying. I tried all kinds of reset like soft,hard and crash but no response. It's not responding to anything except those 5 LED lights.

D-Link DIR-615 :: Device Is Not Responding To Hard Resets

Jul 21, 2009

I have a DIR-615 that is not responding to hard resets.  It was working fine for about a week and then stopped handing out IP's to wireless clients.  I attempted a power cycle and when the router came back up the wireless light was no longer on and it was no longer handing out IP's to Ethernet clients.  The power light is solid, internet light lights up when connected to my modem and flashes intermittently, and the Ethernet lights light up in response to connecting clients.  I have attempted to hard reset the router to no avail.  I also tried statically assigning 192. 168. 0.120 to my NIC to see if I could access the router config but that doesn't work either.  It's almost as if the default ip address and range for the LAN on my router have changed and DHCP was turned off.

D-Link DIR-625 - DNS Server Not Responding Multiple Times A Day

Dec 28, 2012

For the last several months, but progressively worse, my internet drops due to the DNS Server not responding. This happens across my whole network and the only fix I can come up with is to reset the router every time it does this. At this point I am thinking a new router is in order (but do not have the money atm), I am using a D-Link DIR-625 V. C1 Firmware 3.08 router and a Motorola SB6120 modem. Is there another permanent fix for this problem is or my router on it's last legs? Would setting a new DNS Server on my router work?

Cisco Routers :: RVS4000 Stop Responding To DNS Requests

Apr 4, 2012

We have a 25Mbit connection comming in through a cable in the basement, going through a modem that is connected to a RVS4000 small buisness router on the first floor, that acts as the single NAT. Connected to that in parallel we have 4 wireless b/g or b/g/n routers of various cisco/linksys models, one for each floor, each with DHCP disabled.Over the last few months there have been some issues with the router and I'm curious if there is anything that can be done to solve them.The firmware of the router is the latest at the time of this writing, V2.0.2.7
 
1. The router will occasionally lock up and completely stop responding to DNS requests. Attempting to open a website will result in browsers giving their standard 'DNS Lookup Failure' messages. The router will also become completely non-responsive when trying to access it via its IP address (standard 192.168.1.1). No username/password dialog appears.However oddly enough IRC and other chats like skype will still work fine.Restoring Factory settings has not worked. This issue has gotten to the point where this happens about once a day. Restarting the router will fix the issue. While I think the issue may sometimes resolve itself, it could also just be one of the other people in the house restarting it manually.I'm assuming that the router is to blame here and not the cable modem in the basement or the DNS server of our ISP, mostly due to the fact that the router becomes unresponsive and won't let me log in as admin when this happens. also restarting the router, not the modem, seems to fix the issue.
 
2. The router's log is always empty Specifically I have enabled 'Output' and 'Local Log' as you can see here:

3. Issues with some people hogging bandwidth With 25 people and a 25Mbit connection each person in the house should effectively get about 125KB/s of download speed, especially since not everyone is always using bandwidth. However it can happen where one person is, often without knowing it, hogging a large chunk of bandwidth and slowing the network down for everyone, such as downloading multiple large files from different sites, streaming high-quality video, etc.I would like to know if any of the following might be possible to do with this router: See the bandwidth usage per individual MAC or IP address on the network over timeLimit the amount of bandwidth a specific MAC or IP address can use. Make the distribution of bandwidth more fair when a few people are using far more of it than other people.  
 
I have at times resorted to limiting P2P via IPS in the past, and of-course that does work somewhat, but that's not ideal. I'd much rather just know who is doing it, and specifically by how much they are slowing other people down. While the IPS page will list the IP addresses of those trying to use P2P when it's disabled, there is no way for me to really quantify how much bandwidth they'd be using otherwise, and this doesn't at all include things straight-up HTTP downloads.In any case, this router should easily be able to handle ~25 simultaneous connections, right? Are there any settings that I should make sure to enable or set to distribute bandwidth more fairly, given the setup we have?
 
4. The IPS report chart is not readable.This is a bit of a nit-pick, but the IPS report chart is basically not readable because the colors used in the key are identical in color. Can you tell the difference between the colors of 'Network Traffic' and 'Attack Counts' in the key at the top? They could have used any two colors that are at least somewhat distinguishable, even light grey and dark grey would have been better, not magenta and another magenta.
