Netgear WNDR3700 And Motorola 6121 - Lag Spikes From Connection

Oct 31, 2012

I have Comcast cable and prior to a couple days ago, it has always been smooth @ 36mbps download and 5mbps upload. I have a Netgear WNDR3700 and Motorola 6121 connected to my PC via Ethernet cable. Up until a couple days ago, I've been getting lag spikes where my games would completely freeze for a good 2-3 seconds and resume, as if the entire connection dropped and reconnected. I did a speedtest and I was getting around 4mbps download and 1-2mbps upload with huge fluctuation in speed.

I called Comcast and they said they were seeing a "red" signal error from their end so they sent out a tech to my house. He came over, changed some cables outside because they were corroded and that's about all he did. I tested my connection while he was still there and I was again getting 36mbps download and 5mbps upload. It was a quick 1-2 test so everything seemed normal until I started to see lag in games again.

I am getting the same lag spikes, albeit it's not as bad as before but it's still pretty annoying. Using speedtests, I am still getting 36mbps download but the graphs show that there are inconsistencies where there would be sudden drops in speed and picks back up still to show 36mbps. These drops are what I assume are the lag spikes. The upload is also suffering now, dropping down to 2-3mbps and it takes the test about 20-30seconds to load the upload portion of the test. Even loading web pages, sometimes it locks up for a few seconds longer than it should, which is normally instantaneous.

I have tried connecting my PC directly to the modem to bypass the router and am still getting the same lag, probably a little LESS but still the lag is there. My router is has always been updated to the latest firmware.

Routers / Switches :: Intermitted Internet Connection With New Motorola SurfBoard 6121?

Jun 15, 2012

Motorola Surfboard 6121, Every since Com-cast has updated their network (two months ago), my Internet connection is VERY unstable.Com-cast says it is my problem because I can get reliable service at high speed using just my laptop: Win 7, and the Motorola modem. The modem does show high speed connection (blue light) when the only thing connected is the laptop.If I connect the rest of the home network; ,LinkSys BEFSR11 router, Netgear FS #108 10/100 switch, then my laptop. The Surfboard modems light turns orange (lower connection speeds). do I need to replace my NetGear switch and my router? This constant up and down intermittent connection is terrible!

Netgear WNDR3700 - Well Performing Card To Make Up No Hardwired Connection

Jul 2, 2011

I'm going to be moving into a place in the next couple months where I'll have to go wireless on my desktop (until now I've just done Ethernet so I don't even have a wifi card on my desktop). The router/modem aren't anywhere near my bedroom so my gear will be going wireless from now on All my devices are built-in wifi ready but not my desktop.

I would like recommendations as to a rock-solid, reliable, fast and well performing card as I can to make up for no hardwired connection. Especially with BF3 coming out I'm not all that thrilled with being forced into this situation but you gotta do what you gotta do. Anyhow, I'll be bringing my router (Netgear WNDR3700) so I'll have the range and speed from there about as good as I can get, so I'd like a card of equal merit.

One side note...probably not really feasible considering I want speed and performance as a priority, but I would love a card (if possible) without bullshit antennas sticking out of the case, or with external antennas you have to set up on your desk. I will go that route if I have to but man that is an aesthetic nightmare, IMO. The ones that stick out of the back of the case are the worst looking for me just as a caveat.

Motorola SB4200 / Continuous Ping Spikes Of Around 50ms?

Jan 26, 2011

We've had our internet provider and the same setup for about 5 months before this with no problems. I first noticed this in gaming. My ping will stick to around 40-50 in a server, but continually spike to 80-100. I don't notice it all that much, but on others' screens I'm choppy and look laggy.I'm connected to a router, but it seems to happen while directly connected as well. It has nothing to do with others on the network either. The modem is old, not sure if that has anything to do with it, a Motorola SB4200.

Netgear WNDR3700 Behind Firewall?

Jul 27, 2011

I'm in a bit of a predicament. Trying to set up a Netgear WNDR3700 behind a SonicWall TZ170 SP (Standard OS). The only thing I really want the SonicWall to do is maintain site-to-site VPN connections to a few other networks that I work with.

The SonicWall WAN is passing Internet connectivity to the LAN ports as it is supposed to but the hangup seems to happen at the Netgear; it doesn't seem to want to receive Internet connectivity from anything but a modem and it doesn't want it going to any port but the Internet port (IE, it doesn't seem to want to share Internet via the switches).

I'm thinking this may be a limitation of the firmware and that dd-wrt might be the only answer but I thought I'd bring it here first as my last experience with dd-wrt wasn't a good one.

Port Forward Netgear WNDR3700

Jan 21, 2012

I am trying to forward the ports for several ip network cams, that have built in webservers, on this router. I have done this before on my old Linksys router with no problems but the Netgear has me stumped.The only way I can reach any of these devices from the Internet is to map them to port 80. But that limits me to one device, hence the need to forward more ports.All cams have fixed ip addresses so it is not an issue of their ip addresses changing.

New Netgear WNDR3700 Cannot Access Internet

Mar 3, 2012

My old router (a dlink dir-615) works just fine, but I figured I would upgrade and try to run OpenWRT or DD-WRT so that I could have one VPN for all my devices.

Anyway, I took the router out and followed the instructions (power off modem for at least 1 minute, connect modem to router, router to computer via ethernet, turn on modem first, wait for it to fully boot up, turn on router, wait for it to fully boot up, and then run the setup on routerlogin.net. The router is currently setup and I can connect my computer or iphone to it just fine, but I cannot access the internet. It doesn't make a difference whether I'm connected via ethernet or wifi. Either way, I get a "No Internet Access" message from Windows 7.

I've tried turning everything off and starting again. No luck. When I go back to my dlink router, everything works fine again.

So, in short:
Modem + ethernet = internet
Modem + Netgear router + ethernet = no internet
Modem + Netgear router + wifi = no internet
Modem + Dlink router (wifi...haven't tried ethernet) = internet

NetGear WNDR3700 Incompatibility With Atheros AR5700?

Feb 16, 2011

I can connect to my LAN, but with local access only. I've been to the mfg's forums and tried their fixes, driver updates, and manual setups- no joy so I've reset to auto defaults. This laptop connects to several other routers wi-fi without problems. The WNDR3700 solved all my previous router problems, was truly plug and play, and may have cured me athsma as well. The event logs show a time-out during the semaphore portion of the log-in.

WHS Remote Access Failure With Netgear WNDR3700?

Jun 2, 2011

I have been unable to access my WHS when I recently traveled across the US. I have a Netgear WNDR3700 router. My DSL modem is a DSL-520B. I have AT&T DSL (6 Mbs). I have tried enabling and disabling "remote management", forwarding to ports 80, 443, 3390, and 4125 all with no success.Also, I believe (correct me if I am wrong) the remote management address is incorrectly listed as http://192.168.1.2:8080. I have also turned off USB storage in case of a possible conflict I have read about with port 80.

Centrino N6150 And Netgear WNDR3700 Slow To Validate?

Oct 21, 2012

I have numerous phones and laptops that connect to the router just fine and fastThis ASUS laptop (windows 7) with Centrino N6150 is very slow to validate. At least it appears that's the issue. The icon in the tray starts with a ! in the connection, then in about 45 seconds goes to a blue chase circle, then in about 45 seconds connects.istory. I was getting disconnects from the WIFI router on a continual basis. I decided to put the router back to factory settings, did the pin reset etc, did a full setup and now we have this slow connect issue ALTHOUGH I never get a disconnect if I once get connected. Just seems to take forever to get it to connect.I've looked at conflicting IP's, no avail, seems fine. As mentioned, like the iphones connect almost instantly. The HP laptop connects fast (windows 7) but the asus now isn't happy.

I have had a Netgear WNDR3700 wireless router for over a year now, and have had no problems connecting to wireless devices (currently connects perfectly to: windows 7, OSX, Android, and Meego). I have recently purchased a Sony Bravia NX720, which has a built in wireless card. When I connect the television via LAN to the router the internet works fine, however when I connect via my wifi network (i.e. there is no physical connection between the tv and the router) I get the following message:

If I click to watch the network traffic (on the local connection status activity) I can see 50,000 bytes received every second I have updated the sonys and dells drivers to the latest one both from sony/dells site and from atheros download site as well - but it doesn't seem to make any difference The router also states its fully up to date

WNDR3700 Would Connect At 300mbps With Stock Netgear Firmware

Sep 10, 2011

I have a Netgear WNDR3700 v2 that I loaded with dd-wrt (v24-sp2 std). The only real problem that I am having is with the wireless. I can't get anything to connect at 300mbps. Even if I set it to n only it still only connects at 54mbps. Right now I am running it with encrytion off to rule out that causing any problems. and yes it would connect at 300mbps with the stock netgear firmware.

Netgear WNDR3700 / Untangle Worth It For Home Network?

Jan 11, 2012

I've been replacing my Netgear WNDR3700 (currently only serving as wired router and gigabit switch) with an Untangle box.Obviously, only the free "Lite" version would be worth it, as the others are priced ridiculously for non business use. I've had a hard time figuring out from their webpage how the features of the "Lite" compare to the others, particularly how Spam Blocker Lite, Web Filter Lite and Virus Blocker Lite compare to the full versions of each.

Is the untangle router any good? How do its management features compare with consumer solutions?The new web caching feature seems really cool too, especially when multiple systems grab the same large updates or download the same steam games, but at $54/year it seems a bit excessively priced for home use, so I'd probably just be sticking with the base free version.

Netgear Wndr3700v3 Router - Constant Small Lag Spikes

Jun 3, 2012

I've been having this issue with my wireless connection for quite a few months now and up until now I've just dealt with it. With the release of Diablo 3 (whoo!) it's become unbearable with this lag spikes. My ping will be fine, steady around 50-90 but then randomly spike upwards of 400. After a few moments (literally a second or two) it'll drop back down to it's normal speed. This happens in all online games I play, WoW, League of Legends, DotA 2 and now Diablo 3, I have roadrunner and pay for 25 download and 1 upload so it should be more than enough to play the games I'd like, I'm also running on windows 7. I think part of the problem could be the fact that the router is in the basement and I'm on the second story. I have a netgear wndr3700v3 router and I set up a repeater in my room to see if that would work (asus rt-n12 router) and although it has increased my speed, I still have these ping spikes.

WNDR3700 CAT6 - Just Plug Switch Directly Into Netgear NeoTV550

I just ran Cat6 from my WNDR3700 to a netgear NeoTV550. WNDR is in the computer room and the Neo is in the living room. Cat6 had to be fished downstairs, around the bathroom wall and over the solid plaster ceiling. Fun times! My question is, should I add a switch to the connection on the far end, essentially creating a trunk sans dot1.q tagging and then plug the Neo in? Or should I just plug directly into the Neo?

Netgear WNDR3700 Router - Using Wi-Fi Extender / Different Band With Same Network SSID?

Jul 7, 2011

I have basically the following setup: It's a home network, running with a Netgear WNDR3700 wireless router.

Wireless Devices on the Network:
Google Nexus One: 802.11 b/g/n
iPhone (Original): 802.11 b/g
Main Workstation Laptop: 802.11 a/b/g
"Beater/Other" Laptop: 802.11g b/g

Ethernetted devices on the network:
Logitech Revue: CAT-5e

I'm running both the 2.4 GHz and the 5.0 GHz networks over the same SSID. The goal, obviously, is to get everything over to N if possible. I've heard that wireless N has much better signal and transfer rates, is this true? Also, is running the two different frequencies with the same SSID problematic? It's kind of strange, because my Nexus One is having a difficult time staying connected to the network in my office while the main workstation laptop in the same room is getting a much better signal.

[Code]....

What's interesting is that both are running on the 2.4 GHz networks, essentially both not on the wireless n network, which kind of defeats the whole purpose of things. Is it bad to run both the 2.4 and 5.0 GHz networks with the same SSID? If using a network repeater, is it bad to rebroadcast the original network with the same SSID as the source network? It seems that the 5.0 GHz network is getting "clobbered" by the 2.4 GHz network. Is it really necessary for me to broadcast using different SSIDs?

NAS Storage Slow Network Speed - Netgear WNDR3700 Router

Jul 12, 2011

i set-up the D-LINK DNS 323 NAS unit with RAID 1 (dual 2-terabyte 5400 rpm drives)

it works, but it is slow in copying files between my computer and it (8 minutes to copy 7.94 gig file between NAS and my PC via wire).

i am using netgear WNDR3700 gigabit router. replaced the network wires to the latest spec, and my computer has realtek PCIe GBE network adapter.

this is looking more and more like the NAS RAID 1 is the bottleneck.. possibly 7200 RPM drives would have kicked more ass?

Dell :: Random Internet Lag Spikes - Netgear M14xR1 Router

Oct 26, 2012

Since last night 10/26/12 I have been experiencing random lag spikes on all games (Hawken Beta(installed yesterstay), Mechwarrior beta, MW3, and BF3).

* Framerates do NOT drop when the lag occurs
* Lag last for 1-3 seconds
* Lag occurs on both wireless and wired connections
* Lag occurs when no one but myself is on the network and while others are on it as well
* Only occurs while gaming as far as I can tell
* Unsure if other computers on network are lagging because none of them are gaming computers
* I have performed tests using SpeedTest and the ping/DL/UL speeds are normal
* Tried turning off Anti-virus (Kaspersky). No Change
* Ran virus and malware scans using Kaspersky and malwarebytes. Both negative results

Dell :: 3300 Print Adapter And Netgear WNDR3700 Wireless N Router

This happened while switching routers.  The 3300 worked fine on my D-Link Wireless G router (WEP). I was wondering how to resolve it.?

Wireless :: Connection Lag Spikes Every 5 To 10 Minutes?

Feb 5, 2012

I have a problem with my wireless connection. I recently installed Windows 7 Ultimate 32bit OS and bought a new NETGEAR genie router WNR2200. I am experiencing lag spikes in 1-2 second duration while playing games. These lag spikes freeze the game and send my ping sky high (ping 999ms). While browsing the interwebz I don't really notice the lag spikes because they are only a few seconds long.Changes I have made (PC):

Disabled Client for Microsoft Networks
Disabled ANOD Network Security Filter driver
Disabled QoS Packet Scheduler
Disabled File and Printer Sharing for Microsoft Networks

[code]....

Mode: Up to 300MbpsAfter all these changes and tweaks I still get the exact same problem I started out with. The above changes were recommended by users of random forums to fix wireless lag spikes. Using a cat5 cable is not preferred (and perhaps not possible) as I am renting from random people and the router is on the other side of the house.

Wireless Connection - Huge Random Lag Spikes?

Apr 27, 2011

This has been a problem for quite a while now, jumping from Shaw to Telus,I have completely exhausted, and I have no idea what's wrong.I live in a household with another family, and we share internet connections, Telus Fiber Optik, as of now. Me and my brother both have our own computer and are connected via wireless adapter, and the other family has one laptop with wireless connection.

The problem would be that randomly, the internet would slow down considerably, with pings going insanely high, like over 9000ms (not joking).At first,I thought I was just too far away from the router.So I moved to a room directly under the router, and the internet was completely fine for around 1 week, then the random ping spikes started to happen again. Now, I've tried tweaking wireless settings, and checking to make sure its just not my wireless adapter, however my brother's adapter is new, but it has the same problem too, so I doubt its the adapters fault.

Motorola SBG901 Wireless Connection Is Very Slow

Aug 12, 2012

I have Bright House as my ISP and did not want to pay a monthly rent (and an additional $45 for installation) so I decided to buy the SBG901.

Long story short I discovered that the variable and slow wireless speed is because of the wireless feature and not Bright House.

Have tried to modify several settings (as the ones found on Amazon's reviews) but still get 4-5 MB instead of the 7MB that I get with a wired connection and sometimes I do not get any wireless internet at all !

I am about to purchase a modem and a separate router if I can't find a solution for this. Unit is out of warranty so Motorola won't assist either.
