No, the E2500 is a good router (better than the 1200 or 1550 IMO). My current home networks use 5 D Link DIR-655 units, two as routers and the rest as access points. Different brands work together fine if they are support same standards. One advantage of the E2500 is that it is dual band simultaneous -- so if you get dual band or 5GHz adapters for you devices you can leave the 2.4GHz band free for miscellaneous connections. Recall that if any device connects to your 2.4GHz N radio as a G device, all 2.4GHz devices will default down to G; also G has a lot more interference from other networks, wireless phones, headphones, and speakers, baby monitors, microwave ovens, etc.
Every consumer grade router available that I am aware of will experience dropped wireless connection when you reach around 10 or so users -- while they all support hundreds of connections, the radio systems are not robust enough for very many users. There are ways to solve that issue if you expect that problem, which involve multiple access points or commercial quality APs that can get expensive fast depending on the number of connections you need.
Well, Our house very very very rarely has even close to 10 people using WiFi at the same time. Also interesting, could the "G" thing you're talking about be the problem? I remember that option, and I put it to "Mixed". Should I make it B only or maybe even Disabled? I also ran around the house with my tablet's WiFi analyzer, and all my neighbors used 1, 3 and 11. So I use 13, and no single soul uses it also. Besides, there aren't that many people around my house since my neighbors' lots are like 5 meters away from my house lot, not considering WiFi blockage via walls.
About the E2500, our house isn't very techie, so I don't think we have any 5 G Hz devices. I was really considering interference as a main problem, but even direct LAN cables still screw up. My router is really dying, and I can accept that. But is there any reason I shouldn't get the E2500? Like some features I'm paying good money for yet I wont probably ever use in the near future? But for me, It's the average router, that doesn't have bad reviews. I just really really want a DEPENDABLE router. Not something that screws up 5 times a day.
If you really say diff. brands work together then here are the devices in my house:
iPhone 4
iPhone 3GS
2 Nokia's (WiFi capable - My brother's horrible phone, My dad's touchscreen Nokia both hardly EVER uses wifi)
2 Samsung Tablets (School eBooks)
2 working laptops (2 Toshiba's, one is ancient. The other is a satellite, my brother uses it often)
My WiFi Antenna D - Link AirPlus G DWL-G510 Wireless PCI Adapter(rev. C)
My Brother's WiFi Antenna Linksys Wireless G PCI Adapter ( I know, quite vague, that's all it says. Anyway, it's a PCI card and it's default antenna is like 5 or 6 inches long)
My brother's friend's laptop (Some MSI gaming laptop, This is like what... 2 or 3 times a month? Not very often)
Anything gonna conflict with the E2500? Both antenna's say Wireless G, what does that mean?
I thought of a few things that might be conflicting. I only listed items that were around when all this *** started.
2 Cordless Landlines (Both Panasonic KX-TGA710CX)
TV remotes
Microwave (It's downstairs in the kitchen, so meh. Probably not the reason because it's so far. Don't think WiFi even reaches the kitchen.)
That's all I can think of.
But honestly, I'm sick and tired of this ancient router. So yeah, I'm getting the E2500 unless there are any objections, suggestions. I'll try to not be biased towards Linksys, so throw all your suggests at me. I'd say the most expensive I'd go is $100 (Not sure about the prices here, but I only made it in $$$ so you guys can relate. My real currency is Philippine PESO which is Php 43 : $1.)
Again, sorry for the late reply, got school *** to do.
