Where you get get a modern ISDN modem with at least 4 channels? I am 2 miles from Cable and .5 miles from dsl.ISDN is the only option cause I play games online. Would 256K or 128K Up and Down be enough for playing FPS games on xbox live? I cant find any ISDN modems that are new. Only used ones on ebay that I dont know would work on windows 7.
I used to have a Thomson st-330 USB modem for my ADSL network. When I wanted to change my IP i just disconnected and reconnected a dial up connection that does the job instantly! (a wan miniport + a batch file to disconnect/recoannect with my password and username)Few days ago i bought a new modem/router (TP-LINK TS-W8951NS)Before that all I knew was that if I wanna change the ip address (if I have a router) was a batch file with commands ipconfig /release/renew.I now know that this changes the ip of my PC not the global IP! So how would I change it without restarting the router? (When i change something in my router interface page (PVC1.2.3....etc) my IP changed instantlybut how do I do this without accessing the router, like commands and a batch file etc? I just found out that my global IP changed on its own after like 30-60 min :S why is that! and to do so manually???
I have a 2wire Modem connected to a Cisco Wireless N Router, that is connected to another Cisco Wireless N Router. All was working well. In my absence sbc (AT&T) changed the pass word of the 2wire Modem. The 2wire has stoped communication with the Cisco Wireless N Routers. I connected am Ethernet wire to one of the ports of the 2wire, and connected it to the 2nd Cisco Wireless N Router. The signal gets to the 2nd Cisco Router. However, when I attempt to access the Internet on the CPU connected to the 2 Cisco Router, I get an error Message saying that there is a problem with the Modem and/or Router. On the available Networks selection screen I can see the connections that I want. The selection info shows connected. But when I try to connect, the I can't.
I have cable and am using an sb5101 modem and an wndr3700 v2 router. I have tried changing the router mac address with no luck. Also the ip address is dynamic not static verified by bigpond.how to change my ip address.
I have a new Linksys E2100 that was working well with an old Verizon modem. Then recently that modem gave up the ghost and I was issued another one (Westel Model 6100G). I have no problems with internet connectivity when connecting directly from my harddrive to the Verizon modem. I am also not having trouble connecting to the Linksys routher as I am able to see my wireless connection with no problem. However, when I try to set up the connnection with the E2100 in the loop (yes, it's connected correctly) I no longer have internet access.I tried de-installing and re-installing the Linksys software (thinking maybe there was some new configuration that would be auto-detected with a new set-up), but this didn't work. I suspect that if the problem is with my Linksys router and not with my Verizon modem that there might be something that could be done to reconfigure something manually but I do not know enough about connections and wireless systems to trust myself not to mess something up.
I set up EA6500. All kinds of problems with anything on the 2.4 MHz band. My wireless desktop on the 5.0 MHz band was flawless. So I ran Xirrus Wi-Fi Inspector (freeware). The router is transmitting two 2.4 MHz signals! One is the SSID I set up and named. The other one is identical in every way except that the BSSID is slightly different. It is a non-broadcasted SSID that shows up on every device as "Other Network." I was on the phone with Cisco Support tonite, and they were great as usual but had no answer. If you change the channel on the 2.4 MHz band, the shadow network also changes to the same channel (this blew the Tech's mind). We reset the router to factory settings and started over. They are calling me back tomorrow. This router has great features on paper, but so far, it has not delivered.
The Cisco E4200 is supposed to support something called DFS (Dynamic Frequency Selection). These are wifi channels that, due to radar operating on the same frequencies in certain areas of the US, the FCC requires devices using them to do what's called "radar avoidance" -- they're supposed to scan the channel periodically and, if a radar signal is detected on said channel, they have to vacate the channel for a specified period of time (typically around 30 minutes). Because of this, a DFS channel cannot be selected manually by the user -- it has to be selected automatically and vacated automatically in case radar is detected. So, I have my E4200 channel set to "Auto(DFS)"
The list of WLAN channels is here: [URL]
More background: each allowed 5 GHz channel is 20 MHz wide in the US. However 802.11n does what's called "channel bonding" -- it actually uses two channels side-by-side for increased throughput. E4200 owners will notice a channel width setting and one of the options is 40 MHz or Auto (20 MHz or 40 MHz) -- this is what uses two channels combined. I happen to have this option set to "Auto (20 MHz or 40 MHz)".
I discovered, through experimentation, that the router will ALWAYS select channel 149/153 as the operating channel if there are no other wireless APs in the area (channel 149 as primary and channel 153 as secondary). I always wanted to see the AP select a DFS channel, so I brought home a bunch of access points and started occupying spectrum. I put AP #1 on channel 149/153 and rebooted my E4200, at which point it picked channel 157/161. So I put AP #2 on channel 157/161 and rebooted the E4200, and it skipped channel 165 (note that there's not enough spectrum up there for 40 MHz, which is probably why it got skipped) and selected channel 36/40. I put AP #3 on channel 36/40 and rebooted the E4200 and to no surprise it picked channel 44/48. So I put AP #4 on channel 44/48 and it picked...channel 149/153?!?!
Just to be certain that there isn't a certain threshold required to force the AP to select a DFS channel, I moved all 4 APs RIGHT NEXT TO the E4200 such that their signal strengths exceeded -40 dBm, and then rebooted the E4200. It STILL picked channel 149/153!
Just what are the criteria required for the E4200 to select a DFS channel?!? DFS is advertised in the user menu, but I can't find any way to get the AP to select one of those channels. Does the AP *really* support them, or does it just say it does? If the E4200 does NOT really support DFS, then Cisco/Linksys should remove the term "DFS" from the user menu -- it is deceptive!!
Oh, I should mention that I'm in Santa Clara County -- Saratoga, CA. I checked the FCC database on radars and as far as I can tell, there are NO radars on DFS frequencies around here.
So anyone can use this channels without any restrictions and without register this AP.So how can i use this channels on my newely purchased EA3500? from drop down menus only low range is available.ive tried 2 different FW from linksys site (Cisco FW and Smart WiFi FW) in both i cant use this frequences .Also for this router no alternate FW available because inside Marvell chipsets (im not understood correctly why, but i suppose all about "closed FW").Also ive tried to change timezones (in hope that this range is magically appear), but magic not happened. So i have question: why i cant use this 5gHz range when its legal in my country?May be Linksys support watch on this problem and release new firmware for Russia with support of this channels?Also i knew that E3200 have this range enabled on default FW, but not on EA3500.
I have read various forum postings saying to get the best performance from a wifi router you have to use channel 149 or greater and that 36-48 have a weaker signal strength and thus less range/speed.I live in New Zealand and when I select the wireless channel drop list for the 5GHz band it only lists 5 options - Auto (dfs), 36, 40, 44 and 48. I have read forum posts of people stating you should switch to 149 or greater and I have seen screenshots showing the drop list with 149 selected. But I don't have that option.If I check the Status > Wireless page it shows that channel 36 is being used (for Auto).Am I doing something wrong? Do E3000's in this part of the world not support 149 etc?I spoke in a live chat to a support rep who told me that all E3000's are the same everywhere in the world and there was little to no difference in firmware between them. I was also told that channels 36-48 are high gain channels and so there is no need for the other channels, which contradicts other articles I have read which state 36-48 are weaker channels.
I have read many guides about how to forwarding some port in routers, and i did exactly the same as tutorial,after trying many time i just noticed there is something wrong with my router well here the informations.my router model/name UTStarcom AR7RD im using Windows xp SP3 86x my firewall is disable (But i already added the ports i need to open in my firewall)my Upnp are disable in my router well my computer takes a ip from ISP soo i dont need static IP there is no option that let me delete the old useless ports,i searched almost all the sections of my router and i failed to find a thing that let me delete some port.i went to DMZ setting to Active it cuz its the last thing for me to able open some port, i went to DMZ SETTING and tried to enable the check mark for this section i noticed it wont enable, i got no error there just it wont be enable.im watching around its 2 weeks i search any where in different forums and googles.
I've searched high and low across the wide web, but I have found no real answer to this problem;Recently, I bought the DIR-655 because the gods of thunder decided to euthanize my old WAP. The original plan was to mate this up with a Tilgin VOOD-modem (modem and router in one; a heap of s**** in my uneducated eyes) in order to make networking within my appartment somewhat easier.
Got it safely indoors, plugged it in as the manual told me, and got it going (my old WAP was also a D-LINK, so the interface was somewhat familiar). Checked cabled connection, worked fine, and I got the wireless-bit to function as well. But then I, or my Xbox 360 to be right on the money, encountered a little problem. As I understand from a little bit of research, I found out that this was a dreaded phenomenon known as
Before I got the old WAP indoors, I used the onboard router in the TILGIN to do the switching. I used to have this problem back then also, but solved it by opening some of the ports on the modem. Then it switched to "Open NAT", and worked like a charm. Now however, I have ran into a problem I can't dig myself out of. I have tried DMZ, opening numerous ports all the way to the full monty, but I can�t get that NAT to wander into the more acceptable range. And then it became clear that the internet on my laptop was somewhat amputated as well; simple youtube-videos became harder to load (sometimes it actually had to stop for extended streaming!), and this is not acceptable on a 20 mbt DSL-line!
Using firmware 1.0.01, has anyone successfully gotten the E4200 to bond two channels using the 2.4GHz spectrum? I just can't get it to bond. I assume it's a firmware issue, yet to be fixed. I've tried settings Auto (20 or 40), and nada. It has never bonded. The 5 GHz bonds fine. There are a few interferences by the neighbours wifi, but nothing substantial that should prevent bonding. I have this router at school too, and the same thing happens there, with the same firmware, so I doubt it's an interference issue. I'm using WPA2 Personal encryption. I tried auto channel, and setting channels to 1, 3, 5, and 11, nothing changed.
I know I'm not bonded because A. Max link speed is ~144Mbps, and B. using a program like inSSIDer tells me I'm only using one channel on the 2.4Ghz spec.
I have 2 computers running Windows 7. Recently I changed from a Motorola 3347 modem to a Actiontec Q1000 modem. After changing modems I am unable to network the computers, I get error "0x800070035 The Network path was not found".I can plug the old modem in and the networking will work.I have tried to duplicate all of the settings on the Q1000 modem from the Motorola, however there are some different options/settings that do not overlap.
I have recently changed my Router to a Draytek Vigor 2830N from the standard O2 broadband router. When I swap them out I get no internet access via the main PC that is connected via ethernet. However I can access internet via WLAN on any other device. here are the ipconfig details for before and after swap (same)
I am a Rogers Customer (Canadian isp) whch uses DHCP IP address. My set up is like so: SMCD3GN2 Modem with gateway and wireless mode disabled. (i'm using it as a pure modem) 2 of its 4 ports are active, one is connected to my pc directly and the other is conencted to a d-link router. The router is connected to 4 other pc's + some wireless devices. What I want to do is change my IP address ( the pc with the direct connection ) in windows 7. I can effectively do this by simply shutting the modem off for about 30 seconds. Luckily my isp pretty much continuously assigns me a new IP address every time I do this.
The issue is I don't want to disrupt my entire network ( the router ) With windows XP I used to be able to go into cmd and ipconfig/release, then go to my ipv4 settings and set a custom spam ip address/subnet and then go back to automatic and then ipconfig/renew and voila I would have a new IP address. With windows 7 I have no luck. I have tried spoofing/changing my mac address of my network card/adapter and it results in my modem not assigning me an IP address. Is there any efficient way to change my DHCP IP address in windows 7 without disrupting my entire network?
My X2000 modem connect only with small speeds Kbps, it's very weak than Linksys WAG54GP2 MBPS. If I put laptop near the modem speed doesn't change.Only change occurs when I change the channel. But it speed down after a while.I set, N connection, security is WPA-personal, tried some different channel, connection 20-40mhz, update the firmware (there is no problem with laptop, with another modem I can connect with 150kb/s speed) And, if I choose auto setup, security change to WPA, If I'm not wrong.
I took my tv off of the cable, and am watching the Analog channels. Is there a way I can freely watch like USA HD, and such? Also, I have comcast I was going to watch stuff over the internet is there a way around minus switching to business class from comcast to not count toward bandwith?
I am testing a Cisco 1552 and cannot seem to set it to use the 40 MHz channels. In the controller GUI is is set to use 40 MHz channels under DCA for 802.11a but when I go into the CLI and show the config of the AP it shows the channel width to be 20 MHz. If I try to change the channel width through the CLI I get "radio is not disable or ap not set to customize" or something like that. The radio is disabled globally and locally. Is there a way to set the AP or radio to a "customize" mode?
What prompted this was I was testing the throughput on it and can only get a 130 mbps data rate connection to it. The data sheet says it will support 300 mbps with the 40 mhz channel so I was trying to test it atteh higher rate.The HW is a Cisco 4402 with 7.0.230 software on it, 1552E.
I've got a deployment of 1142N APs using a pair of 5508 controllers running 18.104.22.168. We're in the United States and the country is set to "US". I've added the UNII-2 channels to Auto-RF on the controllers via "config advanced 802.11a channel add 100" and so forth. According to the output of " show advanced 802.11a channel", I've enabled every 5 GHz channel that's legal for use in the US:
My confusion comes because the automatic assignment of 5 GHz channels is heavily biased toward just a few of them, with most of the available space being ignored. Here are the 5 GHz channel assignments from a large, single-story building with 31 APs:
(qty 2) 36 (qty 6) 40 (qty 5) 44 [ code].....
A total of nine channels are used (two of them only once) while twelve other channels are ignored completely. Many of these APs are close enough to hear one another, so assigning seven of them to ch. 48 makes no sense.
Looking at my campus as a whole, I've got numerous APs using channels 36, 40, 44, 48, 149, 153, 157, 161, and 165. I've got at least one each using channels 52, 56, 60, 64, 112, 116, and 132. Nothing at all is on 100, 104, 108, 136, and 140. I am using 20 MHz wide channels, between, so all are independent.
Can anyone shed light on A) why my distribution is so heavily skewed toward the first nine channels, and B) how I can learn whether certain channels are being avoided due to the presence of radar, etc, on the frequency? I'd like to take full advantage of 5 GHz by having as little channel re-use as possible.
