Incompatibility issues with Cisco DPC3010 and wireless routers

There is no compatibility issue between a DPC3010 and a router because there CANT be a compatibility issue. Its a transparent switch, so that would be like a dumb switch not being compatible with a router. Also, any compatibility issue would be at layer 1-2 on the OSI model, another words, it would either work 100% or 0%. You wouldn't see a performance issue. 

My guess would be something connecting to your network (which would effect both routers) is taking up bandwidth. Maybe try turning everything else off except the PC you had connected direct to modem. If still a issue, it could be wireless interference. To test for that, compare a wireless connection to the router vs a wired connection to the router. That will show you how much your losing between Modem > Router and how much your losing between Router > PC. 

When we tested this, no other system was within the network. It was only that tested PC, and then, when we tested it on two laptops, they were tested individually as well. It may, as you said, be a case of interference.  Perhaps our channels are congested? I'm not sure why I get consistent speeds with each router(30's on  Rosewill, 10's on the Netgear). It's almost as if something's capped. The only reason I brought up compatibility was from a D-Link router compatibility issue thread I read elsewhere. It was related to the router drivers/firmware installed machines simply not working with the cisco but different modems working fine with those routers.

I'm trying to narrow down a suspect. Thanks for the input. I'm going to see if maybe turning off some of the other 2.5ghz items in the house(cordless phones) will improve the situation. 

siddichan, 

Any device that operates wirelessly in the frequency range of a router will almost certainly eventually cause interference. These devices can include baby monitors, cordless phones, some doorbells, microwaves and appliances with motors that cycle on and off, among others. My daughter even had a set of walkie talkies that would take down my home network the minute she tried to use them.  You may find the following info from our Home WiFI FAQ helpful:

Q: What is the recommended distance between household appliances and my In-Home WiFi device?

A: Cox recommends the following distances between household appliances and your In-Home WiFi device:

Microwave ovens - approximately 40 feet
Baby monitors - approximately 20 - 40 feet
Cordless phones - approximately 20 - 30 feet
Bluetooth® devices - approximately 20 feet

Once you've eliminated devices that could cause interference try running the test again. I've linked the FAQ so you can check out the other info there.

Oh rly? Funny story, I was once a Moderator/Power user on Dlink's forums. Do you mean the issue with the DCM-202? Not that it matters, since you have a valid question either way, just curious.

On thing that will help is inSSIDer, which is a free wifi scanning tool. Be warned, looks like the makers have released the new version as pay only, and made the free version a demo only. You can still find the free version, but I don't want to be posting non official links. 

They also have different tools/Apps you can use on your smart phone. While it won't show inference, it does show you other networks which might be intereing. Also, since the signal meter is more sensitive then the little Wifi signal strength thing, you can use it by moving the laptop around like you were dowsing for water. It might lead you to the cause.

Thank you for not dismissing it. And thank you for the link. When it's a sane hour in the day again, I'll give a go at the scavenger hunt. I'll post my results, so it may help someone else in the future. :)
