Mysterious Speed Issues

First, I would like to apologize if this is in the wrong section. Because I don't have the option to keep my computer connected with an Ethernet cable I thought this was the better place for it.

Modem: Motorola Surfboard SB6141
Wireless router: Linksys e4200

Since about the first week in September I've had speed issues. Before that point I would get between 20-35 Mbps. The speeds were about half what was promised, but the modem isn't in the best place; so I wasn't complaining.

There was a storm Labor Day night. It caused a power surge (I have my computer connected through a surge protector as is the modem and router). Once my computer booted back up I was having connectivity issues and a really slow connection.

For the rest of that week I was plagued by connectivity issues and slow speeds. I tried power cycling and other such quick fixes, but to modest success. The connectivity issue righted itself, but the speed issues remain to this day.

After that storm I get about 10 Mbps. It can fall to about 6 and shoot up to about 14-15, but no higher. My upload speed remains the same though. Regardless of what download speeds I get. Even if the download speeds are lower than the upload speeds. My ping also remains as it was; 16-22ms. Though I do get lag spikes in multiplayer games at times; my downloads don't appear to have corruption issues.

I speed tested other computers, and they got the same speeds as before. I connected my PC to the modem directly and got 70 Mbps out of 75. I disconnected it from the modem, but kept it right next to the router and modem. I got about 60 Mbps.

I've got an Xbox 360 connected to the internet too, but no speed issues before or afterward.

After that I began trying different fixes. I ran a few different virus scans, but got nothing back. I've kept an eye on my networking tab, and it idles at no more than 1.5%. I've checked for driver updates and reinstalled drivers.

I purchased a range extender hoping to fool my PC into thinking it was next to the router; no dice. I got a wireless USB adapter, and got the same thing. I tried it with just the router and with the range extender.

At this point I am truly lost. I have no idea what else to do. I guess I could pick up a powerline kit, but I have no idea what my speeds are going to look like afterward.

Anybody have any ideas?

Sure, just a pair of powerline adapters would work, but the 200Mbps are junk, they usually hit around 20Mbps. The only set that I've found works really well is the Zyxel PLA5205kit that I mentioned, which also come in a passthrough style as the PLA5215kit. Passthrough just gives you a power socket on the powerline adapter so that you don't lose any sockets, although it adds a little to the price. Since you need a pair to work, it is usually cheaper to buy them in a 2 pack or kit form.

I would download and run the free network analyzer inSSIDer from HERE to look at nearby network channels and strength. Just changing your wireless channel could be helpful.

If you do go to powerline adapters, only consider the Zyxel PLA5205kit (or 5215kit that has passthough sockets). I've been testing them and they are at least 3x faster than any others that I have ever used and always stay above 120Mbps on any sockets in my (large) house.

Thanks for the tips. While I was testing channels I found that 2 gave about a 10Mbps boost to my wireless download strength.

However, I am still about 10-15 Mbps behind other computers in the house.

Any ideas.

Do you mean move my router and modem?

If that is the case, I really can't. I don't own this house, and the people that do don't want the modem moved.

If you mean somehow connect the two routers how would I go about doing that?

Not moving your router, but adding a second router configured as an access point (AP) to extend the wireless range. The first and often the most difficult part is to either run an Ethernet cable from the main router to where the AP will sit. If that is impossible, then you can use a pair of powerline adapters (if you want high speed use the Zyxel PLA5205kit, which will do over 100Mbps) to get the signal from the main router to where you want it. Then attach a cheap N router at your end with an LAN port to LAN port connection to the main router. In the AP router turn off DHCP, use a different radio channel than the main router (using the three non-overlapping channels 1, 6, 11). Use the same SSID and passkey as the main router. Give the AP a static address in the AP and in the main router (you will need the AP MAC address for that and it should be on the label).

So if I wanted to cut out the middle man and just use the powerline kits could I go with the 200Mbps?

What is the difference between pass through and non?
