Increased DSL Speed - Cannot Connect To Playstation Network On PS3,

Nov 1, 2012

We had 1.5 Mbps, but we just upgraded to 8 Mbps. Right away we noticed that we couldn't connect to the Playstation network on the PS3, and loading Google would take several tries. In some cases you couldn't even refresh the page to load Google, you would have to open a new tab. We would have bursts of good speeds from online speed tests, ranging from 8.6Mbps down to not being able to load the test, and everything in between. urls... live in Wisconsin and my ISP is Centurylink (formerly Centurytel), a technician came over yesterday and checked our box outside and inside and said that it was our Margin (db), if I remember correctly. Here is the info from my router: [code] The technician ended up lowering our speed to 6 Mbps, and said that everything looked good, and left. The Margin (db) was at 7.3 inside and 9.7 outside before he lowered it, and he thought that if we could hit 10, we would be fine. If that's the case then it seems like the margin is not the problem. If we are using too much speed could we set QoS on a router (would need a different router) to limit the bandwidth?

Speed Immediately Increased To 11Mbps Between Wireless Machines

Jan 21, 2012

Have been experiencing speeds of max 2.5 Mbps for transferring files between Windows 7 machines connected wirelessly to a Billion 800VGT router. A speed of maximum 18 Mbps was achieved. No matter what I did to adaptor settings it was the best possible. Have 6 wireless machines which I cross checked multiple times using Lan Speed Test by Totusoft.I then disabled the wireless security (WPA-PSK) on my Billion 800VGT router and secured the network by using the Wireless MAC address filter. My speed immediately increased to 11Mbps between wireless machines. Speeds to machines on fixed lan increased to 26 Mbps.

Network Speed Is Slowing?

Feb 15, 2012

Is there a way to monitor network traffic speeds. Our companies network download speeds seem to start high, but then progressively slows to a near stop.Downloading small documents start out fast and finishes, but I noticed that the speed slows down significantly. This poses a problem when downloading larger files and documentsThe speed start out very high, but then slows to near zero and results in the file failing to complete.What i need is to find out what is causing the speed degradation and or where our bottleneck is. Is this a setting issue with the browser, security, etc.

Packets Are Being Sent Whenever Receiving Slowing Download Speed?

Aug 6, 2011

Everything is fine except that whenever I am receiving packets, there is a corresponding upstream of packets which is subsequently slowing my download speed.I should be getting ~600kbps, but I am instead getting ~200kbps.The ratio of packets sent/received is almost 1:1.5, and of course when your upload bandwidth is being maxed it starts cutting your download speed.

Linksys Cable / DSL :: WAG160N Slowing Speed While Connecting To Internet

Nov 29, 2011

A few weeks ago my internet speed suddenly became slow. Not so slow you can’t do anything without having to wait half an hour, but significantly slower than usual, and it also has occasional drop-outs. It can’t be an issue with the computers connecting to the router, which it’s doing fine as I can access my router’s setting though the IP address, but with the router connecting to the internet.

Belkin Routers :: N600 Significantly Slowing System's Upload Speed

Dec 23, 2012

At the recommendation of a tech, I ran a speed test (speedtest.net) on my system with my N600 in place. The upload speeds averaged out to 0.21mbps. I took the router out of the system and the speed climbed to an average of 0.37. What is the problem with the router and what need I do to boost the upload speed with it in place?

D-Link DIR-655 :: Slowing Internet Down But Fine When Directly Connected To Modem

Jun 9, 2011

I have been using my DIR-655 for about 2 weeks now with Road Runner wideband services. Starting yesterday my internet became very slow and I discovered the cause was the router. I tried resetting it to factory settings and things will be fine and run smoothly for about 5-15 minutes but after that it goes back to being extremely slow. My speed tests would go from 10ms (normal) to 250-450ms. Before this issue occurred the Dlink was perfect, had full speeds. I am running a wire Ethernet connection.

I am currently using revB and tried upgrading firmware to 2.01NA which had no effect, but make my internet seemingly go back to normal for the first few minutes then nosedive again. I have also changed my speed/duplex settings in Network Config to 1gbs Full Duplex. I've also disabled QoS, and still no change. Not sure what else to do. When directly connected to the modem everything seems fine. The modem is also the provided Motorola SBG6580 which I have called Time Warner to set the modem into bridge mode and have the DIR-655 connected to it.

I own a cyber cafe. I was told that switches are smart enough to distribute the same speed to all the clients. So I was not worried at first. But now if 2-3 customers starts watching youtube videos the rest starts complaining about the speed. I googled for the solution but got none. How to limit the speed,I want to lock the bandwidth of each computer.

Linksys WRT54GL Router Losing Bandwidth / Speed / Disconnects

May 11, 2011

I have a Linksys WRT54GL v. 1.1 that has been dropping connection speed (starts at 54mb, then drops to 48mbs, 36mbs, 28mbs, down to 1mbs) then disconnects, then reconnects at 54 mbs. After a short while, it will drop the speed again until it disconnects and reconnects again. This is the third Linksys WRT54GL that has done this. The first one was 5 years old before it started doing this in February, the second was 3 months old, and now the replacement Linksys sent to me is doing this?

What is going on with my router? I am able to connect fine with the Cat5 cable, but wireless seems to be the problem. Even my phone(s) get disconnected from the wireless router. This problem just recently started and I don't know why, no settings had been changed on any of the routers until after the problem had already ocurred, then the Linksys phone tech support had me make multiple changes.

D-Link DIR-655 :: Download Speed Fine But Upload Speed Is Way Slow?

Mar 17, 2011

I live in the tampa bay area, I have bright house (BHN) as my service provider, which provides a Road Runner Lightning (40/5) package.  I previously used BHN's top tier (20/2) back in July (and prior) with no problems.

After converting to Lightning in August of this year (2010).  Of course, BHN (and every other provider) wants to force a modem/router down your throat, so I had them bridge it (in short, turn it into a dummy modem with no routing). I had an SMC branded modem gateway at the time.  I work from home 2 days a week (so I can spend more time with my kids during morning, lunch, right after work) and this requires me to use QoS to ensure my VOIP work calls don't get dropped, if the family is watching youtube videos or watching netflex. 

My network was as follows SMC Modem >WAN IP>>WAN Port>>D-link DIR-655>>Switch Ports>PC1, PC2, PC3

Everything seemed fine (from a usability stand point) till about 2 weeks ago when my upload speed seemed to grind to halt.  Normally I was able to upload about 200-300K per second, and I noticed this dropped to about 45K per second during a drop box upload.   First thing I did was power cycle both my modem and router (in the proper/usual order).  After they both come up, I start using speed test to find out what my upload speeds were.  I was getting about 39Mbps down, but only .56Mbps up still.  I factory reset my router.... test, similar speeds.  Power cycle all computers (just in case), and then modem/router.  Tested, similar speeds.   Updated the firmware to the latest. Same issue

Called BHN customer service, they factor reset it, but it wasn't in bridge mode.  If I by passed the 655, in factory mode (non bridge mode) upload speeds returned to better than expected states.  If I bridged the cable modem, upload speeds seemed to crash.

Had BHN replace the modem, seemed fixed for a day, then issue came back.  Had them come back out and replace it again, this time with a Motorolla Surfboard modem... same issue.  Fine during factory reset, however after they bridge the modem, upload speeds were fine.  Told BHN I would take it from there.. Connected up the DIR-655, and upload speeds crashed again. (.6Mbps).  Called D-Link Support, and the Chinese English speaking rep seemed to not be listening to me and tried to have me adjust my MTU as well as Wireless settings.  Long story short... the rep was a level 0 id10t and I hope D-link will consider hiring better employees/contractors.  So I was all about to give up and replace it with a DD-WRT capable router (which it takes me a lot to want to swap hardware), when I discovered the wan shaping was on.  Which I thought to myself... nah... QoS has never messed up before... why would it be the cause.  Turned off wan shapping... and voila.  Issue seemed to be insta-resolved.

Unsatisfied with that... I decided to dig a lil deeper. I turned on Wan shaping again, but decided to set the settings manually instead of auto detect.   

Here are the settings I used... (Advanced Tab>QoS)
Enable Traffic Shaping - Checked
Automatic Uplink Speed - Unchecked
Manual Uplink Speed - 5000
Connection Type: Cable or Other Broadand Network

Enable QoS Engine - Checked Automatic Classification - unchecked (this checked seemed to affect my upload speed by about 5-10% during testing) Dynamic Fragmentation - unchecked (this checked seemed to be the worse enemy for upload speed)

While I know I'm not any network guru (still have to use a subnet calculator for subnetting), I think I did a pretty good job drilling down the issue (once I got passed my service provider replacing modems).

Anyways, I've had overall good luck with D-Link products, even have a 5 port 10/100 switch (all metal) from 1998 that works great.  Hopefully, D-Link will just either put more documentation on the web, or hire better employees.

Cisco Infrastructure :: Multicast 224.0.1 Traffic Increased Much

I have started to notice an increase in traffic from all my LAN workstations to the multicast address of, all with the same destination port (79). IANA shows this address as reserved for "experimental testing". Are there any typical applications or protocols that use this multicast address? My first thought was malware running on the hosts but it's a little tricky to prove.

Internet Stops Recognizing New Connections After Increased Usage?

Feb 7, 2013

A short while ago, I had my data backed up onto a new HDD, as the old one was showing signs of failing soon. When I got the computer back, I noticed a problem where I need to constantly hit "Diagnose" in the Wireless Network Connection Status to get my internet working again. When it gets into this stage, several websites continue to work, I don't lose my connection to them. Some websites I can still connect to without a problem. However, many websites, even google, keep giving an error that the host could not be found. It appears that it stops accepting new connections until I reset the wireless card. My Laptop (using wireless) and other PC (Connected directly) have had no issues at all with our wireless router.

Cisco Switching/Routing :: 3620 - Increased CPU Due To Firewall

Jun 20, 2012

I came across a interesting symptom. Refer to the following topology.
host 1 <-> R1 <-> R2 <-> FW<-> host2
host 1 is configured to send syslog to host2, however due to firewall ACL is not configured, this has caused a spike to 99% in R1 which already has 70% - 80% cpu.
My questions are :
1) Even if the firewall is sending RST back to host 1, it should not caused an 20% cpu increase in R1 cpu. Why this is so? Router model is 3620.

2) How do i prevent this from happening in future? This could potentially allow someone to send random traffic to hosts and cause network performance issue. Is there a way to turn off the RST response from the Firewall? This is an Cisco ASA.

Cisco Switching/Routing :: 1456 Does MSS Get Increased With Ip Tcp Adjust-mss Command

May 6, 2012

I just needed more insite into the function of the ip tcp adjust-mss command which can be used to adjust the MSS value in the tcp syn packet which passes that interface. But here is a question which I had. Consider that i have two sets of systems in my LAN one with an MTU value of 1300 ( MSS 1260 ) and with a MTU of 1500 ( MSS -1460 ). If I go ahead and put an ip tcp adjust-mss 1456 (for reducing the packet size from 1500 to 1496)  on the WAN . Does the command only lower the MSS for the set of systems which have 1460 or will it also increase the MSS in the tcp syn packets send by systems with MSS of 1260 ( which can potentially break some communication ).

D-Link DIR-655 :: Motorola SB6141 Link Speed LED On Cable Modem Never Glows Blue

Feb 26, 2013

when I connect my DIR-655 to the Motorola SB6141 cable modem I notice that the link speed LED on the cable modem never glows blue indicating a gigabit connection, it only glows amber indicating a lower negotiated speed.  I am using a Cat6 cable between the two devices and have also tried a Cat5e cable.

When I try and force the WAN port speed to 1000Mpbs in the router interface the cable modem link speed will not light at all with no connectivity. Only resetting to Auto WAN port speed restores functionality albeit at the lower negotiated speed setting.

I'm running the DIR-655 rev B1 at 2.03NA firmware level.

I did connect the modem directly to my PC that uses an Intel Gigabit ethernet card and still had the lower connection indication (Amber) so it seems that the modem might be faulty.

D-link Dir-655 :: Wifi Link Speed Fluctuates On All Devices

Jan 9, 2013

I have a DIR-655 that I have been using for a while (b1 revision).  and suddenly I noticed my wifi speed fluctuates constantly.  My lenovo Y580 sees speed drop to 130 immediately and then it can slowly progress to 1 Mbps until the hardware is all rebooted.  Same happens to my Nexus 7, Dell XPS M1530 and to my roku. I have updated to 2.07 (since 2.10 is advised to avoid). And I have attempted changing channels or factory refresh.What Firmware version is currently loaded? 2.07What region are you located?

What ISP Service do you have? Cable or DSL? Cable (link speed independent of internet speed)What ISP Modem do you have? Stand Alone or built in router? Separate Motorola ((link speed independent of modem)What ISP Modem make and model do you have? Does not matter, router issue.If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.  Not bridged

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.  Independent of issue, not a factor

Turn off all devices accept for one wired PC while testing.  Wired works perfect.Check cable between Modem and Router, swap out to be sure. Cat6 is recommended.  Wireless issue.

D-Link DIR-615 :: Can Bandwidth Be Distributed Evenly

I just purchased a Dlink DSL-2750U today which I am using with my ADSL connection. I have three wired computers using this connection and no wireless systems at the moment. I would like to know if it's possible to share the bandwidth evenly amongst these three computers? The other two computers are hogging on the bandwidth leaving me with barely anything to work with.

Old Tv Slowing Router?

My Internet speed had been ridiculously slow (2mb/s) so I had someone from charter come and check it out. He replaced my modem/router and unplugged the old tv in my parents room. He said that the tv had gone bad and was receiving all types of air waves and sending them through the tv cable and into the router. The problem's already been solved, now I get around 32mb/s download speed, but how the tv received the signals and sent them to the router?

D-Link DIR-601 :: Throttling Bandwidth For Specific Devices?

Bought a DIR-601 for my sister and her kids for their home.  Setup and works successfully.  Sis asked if there is a way to give her laptop bandwith priority over the kids devices.  As is, they are all sharing limited DSL bandwidth.  Reading the manual, I see the QOS feature for specific types of traffic, and other limiters and schedules to shut out certain MAC addresses entirely.  But wondering if this throttling feature exists in the router also.

D-Link DIR-655 :: Bandwidth Limited Guest Zone?

Apr 28, 2011

I'm wondering if there is a way to prioritize traffic on the router's main WiFi over the guest zone or if there is a way to limit the bandwidth on the guest zone.

Ideally, I'd like to keep a locked primary WiFi for high-speed usage (I know, nothing it really ever secure) and an open guest zone for low-speed usage to whomever wants it. As far as I can tell, the DIR-655 doesn't support this kind of configuration.

D-Link DIR-655 :: Settings To Limit Bandwidth From Router?

Jun 11, 2011

I just purchased a 100M fiber line to go with a brand new D-Link DIR-655 router. Before plugging in the router, I tested on my laptop directly from the modem and had great result speeds of 98M/97M. I connected the router, then plugged my laptop to find I was only getting speeds of about 10M/6M. This was true for both wired and wireless connections.

I took a look at the router settings. I turned off QoS, but that didn't work. One thing I did see was the WAN was set to auto. I attempted to change that to 100mbps or to 1000mpbs. However, when I did that my modem light that shows a 100M connection is active turned off and I couldn't get internet. I was only able to get a connection if I left that on auto. Is there a setting somewhere that is limiting my bandwidth from the router?I reset the router twice and checked to find I had the latest firmware. Is there something that I am missing? I have always been a Linksys fan, but wanted to see how D-Link is.

D-Link DIR-655 :: ITunes Killing Bandwidth How To Control It

All are hard-wired (Ethernet) to the DIR-655. How to throttle iTunes? I did some research and found that I am apparently not the only one having this issue.I'm about to bail on iTunes entirely and try to get used to Miro, which does allow bandwidth control.

D-Link DSL 2640B - Does It Load Balance Bandwidth

Aug 30, 2011

I have a D-Link DSL 2640B on the way which I plan on using to replace my 2Wire modem. The 2640B is a combination of a modem/wireless device. Does it dynamically load balances the internet connection? Sometimes while I'm playing online games on my PC and a few others are using the internet for browsing or Youtube, I lag A LOT. Latency shoots up from 10 to 200. QoS goes to ****. And I only need 0.50-1Mbps to keep a steady online play. This was the problem with my 2Wire. So does the 2640B load balance the bandwidth?our max speed is 3.5Mbps according to the ATT Rep.
