Cisco Routers :: EPC3825 - Very Slow Internet Using Wireless?
Aug 2, 2012
The other day I decided to upgrade my old 10/2Mbps connection to a 100/5Mbps cable connection and my ISP gave me the EPC3825 router. When using an ethernet cable everything works great and my speedchecks max out every time, the problem is that I can't have cables all over my apartment so I'd like to use wireless. With a computer located right next to the router I've gotten as high as 20Mbps and usually I'm left at about 3Mbps. I'm aware that using wireless can result in a small drop of speed but this just seems too much, especially considering the fact that I ran a steady 10Mbps when using wireless on my old connection.
Model:Cisco EPC3825
Vendor:Cisco
Hardware Revision:1.0
Bootloader Revision:2.3.0_R3

Recently I placed an Cisco SRP 526W, but this modem is acting quite strange. I have configured an ADSL connection, some NAT forwardings and a VPN tunnel, all of this is working fine. When the Cisco is booted and running, everything runs smooth. Internet is working nice, I can connect over the VPN tunnel to the internal network and so on. The problem is that after a while, mostly after a day or two days, internet browsing is showing problems. IE can't display the page and I have to refresh 1 on 2 times to reach te webpage. I can't connect over the VPN tunnel to the internal network or the internal ip-address of the router, the router is not responding on ping request on the internal ip and external ip. The NAT forwardings are still responing though.
After a reboot everything is running fine again, but I can't let my customer reboot his router each day.
From the ZyXEL modem/routers we used to place at our customers I know the NAT table runs full and I had to use a greater value

I've been having trouble with the internet connection speed on my Mac. I originally noticed the problem when my mail kept timing out whenever I sent an attachment, I went to different forums trying to find the solution but nothing really worked, so I found work arounds for the email and lived with it. Recently the company I work for moved offices and I was no longer behind the RV082 and my internet ran better dispite the slower connection. Once we finished moving, I needed to use the Dual Wan Load Balance feature of th RV082 so I set it up in the new office and my internet was slow again. Unfortunatly in the new office there are several more Macs than just mine so I really need to get it working. Currently we have 2 seperate networks for PC and Mac and I really need to get them on 1. Is there a setting I may have overlooked or is it not going to work with Mac.

I bought a new connection with this router, and the first time i tried to access it it had the default <blank> username and password it, so i changed it. But now i really don't remember what it could be. I tried to reset the router, but it still didn't clear the password. I tried to contact my ISP, and they said they can't access my router remotely, i had to reset it myself. I've tried to reset it many times (holding down the reset button for 10-100 seconds), but by PASSWORD won't be reset.
How can i reset it? Is there perhaps any other reset trick for it?

After upgrading the firmware on my RV042 router to version 1.3.13.02-tm, I am experiencing very slow Internet response on most sites. In some instances, when the page does load, it lacks many graphics. Frequently, I also receive a "server not found"error. In all cases, reloading the page (once it has loaded) results in a complete page display. This is occuring on two MacBook Pros and also on an iPad. The router is a version 1, so no further upgrades are available. I contacted support, but since it is out of warranty, they are unwilling to assist. Prior to the upgrade, everything worked fine, as it has for 5 years.

We are having several issues with the new batch of RV016 (rebranded as cisco and with cisco firmware. The Cisco RV016’s are configured to load balance aDSL internet access from 4 Cisco 877 modems/routers. Ports used are WAN1, WAN2, WAN3, WAN4.
Issues are: WAN 1 port resets to 0.0.0.0 regularly and traffic on WAN 1 fails DNS fails regularly behind the RV016 onlyIntermittent internet connection behind the RV016Slow internet connection behind the RV016Extremely slow DNS query and reply behind the RV016 (DNS resolve takes 1min -1m30)
The issues above are reported from different deployment sites and with different scenarios.
We also test above with Code...

My ISP tested my connection and told me my signal is very weak. I can no longer play games online because I lag tremendously. I can't steam videos while someone else is using the internet either. Also I can't access it on wireless devices unless I am in view of the router. I'm not sure what caused my connection to suck butI have the essential plan from cox.com. When I test my connection on speedtest.com I average 75ms/ping, 3.25mbps/dwnld spd, and

I'm using Cisco EPC3825 cable modem for my home network, and wondered a thing, that if I set up modem to work in router-mode, my real connection speed slows down to around 5-7Mt/s, when using modem in bridged mode, my connection speed is close to 15-20Mt/s. My serviceprovider provides 200/10M speed to my modem, and they've checked, that modem is working with 204/10M speed, and computers works also, if using modem in bridged-mode.

Recently I bought RV215W router and after installing it in my home network; I started experiencing very slow internet connection over wi-fi. Wired connection to this router are working fine. After several hours of trouble shooting, I am able to isolate the slow internet issue to Wirelss N connection. Wireless b/g works fine.
Router is using 1.0.0.16 firmware. I tried to check is there any latest firmware upgrade for this device. Couldn't find any firmware related information in cisco web site.
One another point related to USB WAN; I am not using any USB for 3G connection. USB indicator is keep on blinking.

I purchased a Belkin N-300 router, model F9K1002V4, about 6 months ago, and recently upgraded my cable internet service to a 20+ mbps level, in hopes of improving the speed of my wireless devices. The speed on all of my wireless devices (a new laptop, ipad, and iphone) is still below 1mbps, even when I'm in the same room with the router. The speed on my wired computer registers above 20mbps, so I don't think the problem lies with the cable internet. I have tried to download the firmware update on Belkin's site, but my computer says it doesn't have the right program to run it, and it can't find the program on the web. I sent an e-mail to Belkin customer service, but they just sent me an automated reply, referring me back to their website, with the firmware update that I can't access.

I have a RV220W operating in 2.4GHz N-only mode. Channel bandwidth is set to 20MHz, channel to 6 (a site survey shows that channel as completely clear), WPA2/AES. I am connected to a TrendNet wireless bridge. The admin page for that wireless bridge shows a link quality of 100% with a signal strength of 71%. If I select a higher channel (11), the signal strength drops to 51%.
I have a Windows 7 PC connected to the Trendnet bridge and a Windows 7 server connected to the RV220W, both via a 1Gbps LAN port. When I transfer a file from the server to the PC or vice versa, I get a lowsy 2MBps (~20Mbps) transfer rate. That seems awfully slow. I tried channel bonding from 20 to 40 MHz

I bought my own modem, a Motorolla Extreme something or other, is a DOCSIS 3.0. My router is a Belkin N150. When I plug my desktop computer directly into the router, I get speeds upwards of 50Mbps. The wireless, however, gets about 0.15Mbps download, but as much as 12Mbps upload.
I know it's not computer specific, because I plugged my laptop directly into the modem and got the full speed. AND I put a wireless adaptor on the desktop and got the slower speeds.I live in a densely populated area and there are 27 other (visible) wireless networks available (all locked, unfortunately. Otherwise I wouldn't be in this situation in the first place). So I tried every channel, doing a speedtest with each, and I got almost identical results each time: 0.12-0.17Mbps download, 11-13Mbps upload. I can't imagine that getting only 0.15Mbps could be a result of a channel being clogged, but I tried it anyway;

It should be known that this is not MY specific issue, it's a friend's issue... but I am posting it for him as I know nothing about networking. Don't worry though, anything you post here I will relay for him to do.Is this a wired or wireless connection issue?
Wireless
How to run and post an ipconfig /all output of the computer(s) in question for review.Here it is:

So here's the deal, my friend has horrible down speed, usually less than 1MB/s according to Speedtest.net, sometimes it hits 2MB/s. However, his brother's in the house have at least 17MB/s, which I can assume is their actual speed that my friend should have... however, he specifically does not.He had a very old wireless card that was installed on his motherboard (desktop PC) that I assumed was the issue upon him first telling me, and from the issues I was personally able to see. For example, he'd constantly disconnect... his internet would just die for him specifically, and then come back. His brother's never lost internet when he did.
After that, I figured his very old wireless card that was installed was just kicking the bucket, so I instructed him to replace it. He went out and bought a new wireless USB adapter, and then uninstalled the network card.Even after all of this, his internet is still poor in terms of down speed. HOWEVER, rather than his internet dying for a few minutes at a time every so often, his internet "stays connected" if that makes sense? For example, we'll be on Skype in a conference call, and his internet will be loading pages very slowly, and Skype will constantly show that it's going from "green - online" to "gray circle - connecting". During this, he's still in Skype, but it's very poor quality from him speaking, and laggy as well.

I've just had a custom computer built and I seem to have a problem with my wireless internet connection. I have a Realtek 8185 extensible 802.11b/g wireless adapter. My computer recognizes my house's network and is connected to the internet with a good connection, but when I open up my web browser it takes a very long time for the page to load and sometimes never does. The laptop I'm on right now is connected to the same internet and it is running just fine. I've uninstalled the device and rebooted to have the driver reinstalled but the problem still occurs.

I purchased a Dell Inspiron 15R at the weekend and I am having problems with the wireless internet speed.I have Virgin Media broadband in the UK, my package is 50Mbps. This is via a Virgin Media super hub and is only 1 month old.The internet speed on my new Dell is very slow in comparison to my old laptop (an HP) so I tested the connection using Speedtest.net. [code]
As you can see the HP is consistent on both the wireless network and hard wired but the performance of the Dell is excellent on a wire but terrible on wireless.Some further info - I bought Norton 360 with the laptop, the above results were achieved with that installed. I have since uninstalled that and there was no difference to the speedtest.net. I then turned off the windows firewall and again it made no difference to the results.

I used BT previously without any problems but now use Orange and now using the Internet downstairs is useless(weird flat configuration). The router is upstairs, next to TV(same location as the BT router). I dont know why the wireless Internet signal has become very weak. The only way I can use the Internet if I sit a few feet from the router. Even then, streaming videos on youtube still takes a while compared to BT. This affects all devices using wireless connection - even my Iphone is useless when used downstairs.
Signal interferance/ hacking? Router? Wireless adapter is up to date.

I just set up a new computer with win 7 - 64. The cable broadband download speed is less than 1 meg/sec. My wife and daughters computers, which are wireless, see now slowdown. My computer is connected to the router thru the ethernet connection. The previous computer using win xp - 32, plugged into the same router had no unusual speed problems. I did turn off the windows 7 firewall. Did no good.Could there be some incompatibility between the router and win 7 - 64?? Are there some settings that need changing?
