Networking :: WRT54G Very Slow Performance

Feb 24, 2012

I have a shitty WRT54G right now, and its slow as heck. I was thinking of getting this:

URLS ,I know the later is a modem and a router as opposed to just a router in the first link.I have comcast, I hear it uses Docsis 3.0 right? Mine is a 2.0 modem right now.

WRT54G Performance Improvements From Router Upgrades

Sep 12, 2011

I'm running a WRT54G as my main router with an old Buffalo router (125g I think) as a repeater. Both are running DD-WRT.

I'm looking at upgrading to a pair of netgear 3700's; also capable of DD-WRT. These have several times the RAM and ROM of the stuff I'm running now. The processor is also about 3.5 times faster as well.

If I do this, should I expect to see an decrease in ping (gaming) or an increase in general performance of the network? Also, there is a lot of video streaming going on, but little/no torrenting. We only run about 5-6 devices on the wireless network, but it has to span 4 floors.

Cisco WAN :: Why 2811 Performance Is So Slow

Dec 18, 2011

I recently inherited a small network. There is an existing 1.5mbps Internet connection (fa0/0) (includes MPLS as well/same provider). We added a new ISP that allows for 50mb down/5mb up. I added the new ISP to fa0/1 and modified the NAT overload statements accordingly. I alo changed the default route to ONLY use the new, faster ISP connection. Using speedguide.net, I am only able to get 6 to 10mb down, most of the time. if I plug a laptop into the cable modem then I get 37 to 50mb down. Why the 2811 is so slow?
 
I have attached the config and various show outputs (nat, sh ver, memory, etc.). the file called "latest logs" contains a "sh ip traffic, sh int switching and a sh proc cpu sorted". [code]

Cisco Switching/Routing :: 3750G Stack Slow Performance

Nov 19, 2012

I am currently having performance issues running a 3 x stack 3750G (different models) as a core for a network of roughly 12 x distribution switches. [code] As above, I have a 12 port Fibre switch and 2 x 3750G-48 port switches. [code] I tried to change the SDM to route but hit another issue where the 3750g-48 does not support SDM route so I had to revert back to desktop VLAN.Could the SDM Template be the reason for slow performance? If so which SDM Template should i use as this is the Core L3 switch.

Both internet conections are idle and the performance is about 2 or 3 kbyte/s My question are if I should I enable any of this:

- Agresive mode
- NAT Traversal
- IP Compresion
- Dead Pear Detection
 
How can I troubleshot this slow performance?

Cisco Switching/Routing :: 861 Router - Slow Internet Performance

Jul 21, 2012

I have a new 861 router which I have connected to my home broadband cable modem. Got it all working okay and I have access to the Internet but its not as fast as it is if I connect my laptop to the modem.
 
My Internet is 60mb (was 100 but I downgraded). When I cannot my laptop directly to the cable modem, I get 60mb download speed on speedtest.net If I connect the router's WAN port back to the modem then I roughly get about 40mb, sometimes even 50.
 
I do not have any IOS firewall configured on the router, just basic ACLs to stop SSH and TELNET from public networks. If I do enable firewall then my Internet connection halves itself. I have read around that this is the case with ios firewalls on these small routers so I've disabled the firewall but I still don't know why I cannot get full Internet speed.

Networking :: Configuring Multiple Routers WRT54G

Sep 1, 2011

I'm trying to troubleshoot a wireless network at an Inn which is shared among three buildings. The internet at the main building works fine.

However there is a WDS set up for the other two houses that are part of the property. The network is a bit of a mess IMO. The main problem is that routers on the end of the WDS chain work for awhile after booting, but frequently stop issuing IPs. When a device tries to connect it says unable to configure IP or something like that. Rebooting the router always fixes the problem.

My networking knowledge is very limited but I think some settings must be incorrect. I will try to described the setup here..

All of the following routers are WRT54G's with DDWRT

Main router: 192.168.1.1 [different SSID that WDS], all routers forward DHCP to this router
WDS router 192.168.1.3 at main building is connected to an cantenna that shoots the signal over to 1st house. Gateway & Local DNS set to 192.168.1.1
WDS router 192.168.1.4 at that house is the main AP for that house and gets its signal from 1.3's cantenna. Gateway & Local DNS set to 192.168.1.3
WDS router 192.168.1.5 under the deck at the 1st house picks up that signal from 1.4 and uses a cantenna to send it to the 2nd house. Gateway & Local DNS set to 192.168.1.4
WDS router 192.167.1.6 under the deck of the 2nd house gets the signal from 1.5's cantenna. Gateway & Local DNS set to 192.168.1.5

The IP configuration problems happen at the 2nd house with 192.168.1.6. I believe 1.5 also has IP configuration problems but that router is not used other than to transmit to 1.6. Again rebooting the router fixes the issues temporarily. It works for a couple days up to a couple weeks before the IP problems start.

Mac addresses for the WDS are set of course. I have been trying to experiment with settings for awhile, but do not really know what I am doing. I am not the one who set this up.

Also under the Advanced Routing tab,here are the Static Routing settings:
192.168.1.3: Destination LAN NET: 192.168.1.0, Gateway: 192.168.1.1
192.168.1.4: Destination LAN NET: 192.168.1.3, Gateway: 192.168.1.1
192.168.1.5: Destination LAN NET: 192.168.1.4, Gateway: 192.168.1.3
192.168.1.6: Destination LAN NET: 192.168.1.5, Gateway: 192.168.1.4

Update: looks like STP should be enabled for WDS? Going to try enabling that I guess.

Networking :: After Power Outage Router No Longer Working WRT54G

Feb 10, 2011

Two days ago there was a quick power outage here, just one of those flicks off flicks back on deals, but when it came back on I noticed my internet wasn't working. Couldn't figure out what the deal was so after trying a few other things I ended up eliminating my Linksys WRT54G router and just using my DSL modem. Internet works fine.

Now, I've always been kind of sketchy on networking stuff, but I don't think there router is broken I just think it's been reset or something and now I don't know what setting I need to change to get it back to working order.

Here's the kicker though. I had the DSL modem in bridge mode and the router handling traffic before but I had a huge issue with that where my Steam would only download at 10-15 KB/s. Not only that but it would take forever to login and crash constantly. This would happen on my brother's computer too, which is on the same network. I could never figure out how to fix it as forwarding ports had no effect and every other fix I could think of amounted to nothing as well. Hell, I even did a fresh install to no avail.

Now going straight into the modem my Steam is downloading at full speed and there's no slow login or crashing issues. The thing that boggles my mind though is that more than once before I tried doing this very same thing, going straight into the modem, and it didn't fix the problem.

Ideally I want to get the router back up and running and keep my Steam in full working order, essentially to have my cake and eat it too, but the priority is to get the router back up in running as I have another PC on this network, plus a 360, a PC, a wireless printer, and two Wii's.

Networking :: Home Network Very Slow Between PCs WRT54GS

Mar 13, 2011

I've just setup a box with Windows Home Server 2011 RC. It's a AMD X2 with 3GB RAM. Everything is fine with that, but I'm noticing my internal network speeds are pretty slow. I'm seeing on average 0.8MB/s transfer speed between my PC's and the server, and between the PC's themselves. I have everything wired through a Linksys WRT54GS router.Is this as much as I can expect from this setup? It's painful trying to copy media files (music, pictures and HD video) to the server at such slow speeds! What would I need to do to get better speeds? I'm assuming a different router could do better.

Networking :: Wireless Slow - 802.11g Works Well With D-Link N 300

Nov 17, 2011

I recently changed internet provider and rented a D-Link N 300 Router. On most days everything works well. However on some days the internet connection on my new laptop that has Intel Centrino Wireless-N 130 network adapter get really terrible (usually on Friday and Saturday). At first I thought that the problem was with provider, but now I find out that my old laptop that does not support 802.11n (only 802.11g) has excellent internet connection (at the same time when the new laptop struggles).

How can I troubleshoot what is causing this problem - the laptop network adapter or the router? Is there some setting for network adapter to force using 802.11g?

My laptop is running Windows 7, if that matters.

Asus RT N16 - Would Fast Ethernet Switch Slow Down Gigabit Networking

Nov 4, 2011

I have setup an Asus RT n16 with 3 computers that support gigabit ethernet and a media server on one floor. On the other floor I have set up a fast ethernet switch (connected to my asus router) which is connected to several fast ethernet enabled computers.

Would the fast ethernet devices slow down the entire gigabit networking to 100mbps connections on my floor - similar to how a wireless n network running at 300mpbs must slow down to 54mbps when a wireless g device is connected to it?

Networking :: Internet Very Slow Unless Reboot Router Every Few Days WRT160N

Mar 10, 2011

A few weeks ago, I noticed that my Internet connection had slowed down to a crawl. I waited a few days hoping it would go away on its own, but it didn't get better. So I asked this question about how to make it faster.

The problem went away after I updated to the latest firmware, so I didn't follow up too carefully. But every few days since then, my Internet has slowed down again. Unlike before, all I have to do to fix it is open the router administration page and press the "Reboot" button. Nothing else seems to work, though I'm sure there are options I haven't tried.

If it makes a difference, my girlfriend and I both transfer large amounts of data fairly routinely for school (videoconferencing, downloading entire recorded lectures).

The router is a Cisco/Linksys WRT160N v3 that's about a year old. Most of the time, it deals with just two standard Windows 7 laptops.

What could be causing these slowdowns, and how can I get rid of them?

I installed dd-wrt on my router, and I seem to be getting higher and more consistent speeds. Perhaps more importantly, my memory use is fairly constant.

Home Network Very Slow - Using Spare ADSL Router And Homeplug Networking?

Apr 17, 2013

Today I set up a home network:Cable router plugged in to......Homeplug network, (D-Link DHP-307AV/B 200 MBPS PowerLine Homeplugs) plugged in to a LAN port of......a spare adsl router configured as per here: Connecting Additional Routers | Tech Support Forum...with two desktop machines plugged into the LAN ports of the ADSL router.Both of the desktops have got similar specs, are equi-distant from the ADSL router, and are both connected using Ethernet, not wireless.One of them gets a 9MB/sec ADSL [URL]download, the other can't even bring the webpage up and times out if you ask Google to do a search.Taking out the adsl router and plugging the desktop straight into the homeplug gets a network speed of ~13MB/sec on [URL].Plugging a computer directly into the cable modem gives network speeds of ~40MB/sec on [URL] How can I improve on this, and have it so that both machines can access the Interwebnet at a decent bandwidth?

WRT54G - Wireless Network Very Slow On Laptop?

May 8, 2012

The WRT54G is located upstairs in the game room. The entire house is also wired with Ethernet. I mean every single room except the nook. Well guess where my wife has her laptop set up, yup the nook. She wants wireless. And she insists on staying in the nook.

If I take the laptop in the living room (downstairs and closer to the router) It gets 12Mbs. If I take it upstairs near the router it gets 18Mbs. But in the nook (downstairs) it gets 2Mbs. My wired desktop is currently pulling 19Mbs. I have half a dozen WRT54G's stored in a closet. Should I setup a wrt54g as an AP or should I buy a WAP54G (ebay $20)? I have an Ethernet port in the living room, which is directly across from the nook. I tihnk If I had an AP there then problem would be solved.

Does the signal supposed to degrade that much when passing thru walls?

Linksys Wireless Router :: Win 7 Wifi Causes Wrt54g To Slow Down 20x

Apr 5, 2013

My wrt54g (firmware old - v1.00.6) has run fine for years until my daughter got a laptop with win7. All my other systems still run XP or win2k. I only run wireless with her win7 and one netbook with xp, all the other connections are wired.
 
Going to speedtest.net and after I reset (pull power) the router, I get 20Mbps download. After the win7 wifi runs for a bit, download speed drops to 2 Mbps or less. It seems to be after she goes to you tube and starts watching videos. If I reset again, it immediately goes back to the full speed of 20. I measure this after she's taken her laptop off the network. So, whatever her win7 is doing, it stays that way after she disconnects (i.e. slow on my other systems) until the reset. I also measured the speed on her win7 system and it also would slow there as well and speed up after a reset (for a while).

WRT54G - Internet Slow Down And Upload Tests Not Working?

Jan 6, 2011

So I've noticed a big speed drop in my comcast internet. I went from routinely scoring over 20mbps on speedtest.net to around 11. Also, the upload test fails everytime. On every speed test site I've been to, the upload test completely fails. I haven't changed a thing so I have no clue why this would happen, but maybe it might have something to do with the speed decline.

I have an old WRT54G router that I've had for almost 10 years and I was thinking that maybe that was the problem. So I tried directly connecting my modem to my rig, but for whatever reason, I couldn't get it to work.

I can build unbeatable gaming rigs and program like crazy, but I just do not have networking in my skill set. It confuses the hell out of me and always seems to be completely random. What I can do to isolate and resolve my problem?

Oh, on one of the upload tests I got the following error.

"Trial measurement failed. Client can't send/receive UDP packs to server port 8601".

After installing the correct drivers for wireless internet I was able to pull up the list and find my network on it.When double clicking on our wireless network it asks for a network key (also called WEP key or WPA key).Now we have a password for our network, but after an exhausting amount of tries that won't work. I not sure if that is what its looking for. In our apartment we run mac OSX, windows vista, etc., but usually the password for the network is satisfactory. I have never ran into this problem.I hate to be a noob, but I don't know where to go from here.

Networking :: Fixing Networking With DIR-655

Mar 2, 2011

Having some serious problems on the networking front here at home. I have 3 PC's and 2 Xbox's that run constantly. Our Internet bandwidth is Insight's 50.0 which is 50Mb download speed 5Mb upload speed. The problem we're having is this. Ever since we upgraded from dual 20Mb lines on a Cisco RV042 to a 50Mb on a DIR-655 we've been having latency issues. I have everything turned off in the router. It's basically there to give out IP numbers and thats it. All security is handled from the PC's themselves. Bandwidth tests are fine, I sustain download speeds above 7MB/s using download managers. But pings are terrible. Xbox live is terrible, PC online gaming is terrible. Pingtest.com is terrible. Only when behind routers. I've tried it behind 3 seperate routers. The DIR-655, the Belkin f5d8236 that insight provided me, and the cisco rv042 originally used for dual wan routing. all of which are met with serious failure.

If I plug directly in to the modem pings are fine. Add a router and pings go to shit.

Inconsistent Performance Through Repeater

Jan 1, 2013

I have a fairly large area to cover with wireless, and set up a second router to act as a repeater. The signal works great, other than being extremely inconsistent. Sometimes I get a speedtest of 18 ping and 7 mbps DL to a nearby server, and 10 seconds later it's 300 ping and 2 mbps. There are no problems when using the primary access point without the repeater. Where should I start in troubleshooting? I can't see why there would be such terrible consistency since much of the time the signal strength is fine. It's purely a problem of dropping the connection often.
