Wireless 1/4 speed of wired

Hey, just bought acer aspire 5685 model with intel pro/wireless 3945abg.
Wired desktop gets to 5-5.6mb/s dload and 0.6mb upload.
But my laptop with wirless gets only 0.8-1.3mb download and 1mb upload.
Tried changin channels - nothing, diff modes - nothing, on/off WEP nothing.
It seems that my wireless connection is limited to 1.2-1.3mb but at some tests it drops to 0.8mb so not sure if this is the case. Furthermore cant find speed setting anywhere, so cant really say whether it is limited or not. Using speedtouch 780 wl router. Had a sony vaio a few months ago. The first few days internet was good, showing 4-5mb on wireless, but then suddently started to fluctuate badly and most of the time i could hardly get pages opened.
It must be wireless as wired is all fine.

thanks for the help in advance.

It sounds like your WiFi router is running 802.11 B, you'll need 802.11 G in order to surpass a 1.3MBps download speed.

 

How did you get 5-5.6mbs download? I subsribe to the fastest cable service available and I only got ~1.5-2.


Anyways, besides 802.11G, you could also consiser 802.11A and Draft N. They provide the fastest wifi available. The pre-n router can get faster than 10/100 Mbs wired connections

 

Well not really syre about this download speed, i just use speakeasy speed test which shows download speed at 5-5.5mb.
Well on router it says b/g, tried to change modes on laptop from b/g to g and to b. No difference.
Got another problem. Took laptop to other room, its like 10m away from router and speed became super slow (from excellent to very slow).
What now? this is realy annoying :/
Thanks in advance.

Welcome to the world of wireless. There are a lot of things that affect speeds on wireless. Drivers, phones microwaves, and metal object can block it. And there are wireless cards out there that are totally JUNK. If your number are in MB/s and not mb/s they are not too far off for a 54g (mbps). Minus overhead and your down to the 30-35mbps throughput.

 

hmm, im not really sure then, cuz as i said in my previous post sony vaio worked just fine for a few days reching 3-4mbs. thanks for response ill look out for existing threads on that.

 

I get the same speed on my desktop as on my wireless.

1.5mbps down
256kb up

I have a Linksys WRT54GS Router on wireless G with an Intel 3945 ABG.

And yea, right now there are plenty of services that offer speeds in excess of 1.5mbps and its not that much more expensive.

 

Ok, this is really getting ridicilious now. As I didnt mind wireless speed being 1/4 of wired it was enough for me to surf and play cs (status: speed @54MBs, signal: Very Low/Low, i guess that was the main reason for 1/4 wired). But recently I my wireless just cracked, now i get speed @54mbs and signal jumping from low to good, but my internet is comparable to 56dial-up. Now it gives me this:
150-200~kbs down
150-200~kbs up
I havent touched the router since i was pretty much happy with my connection and now its almost dead.
Any ideas what it might be?
appreciate any help

Just tried something and dont know if its relevant, but when i switched my computer wired to router, my wireless speed went back to normal.
Yesterday when both computer were on, most of the time i had bad speed, but there was those delightful minutes when it was working fine for 30-60min before crashing again.
Btw, all p2p file sharing programs were off this morning and it was just idling.

 

are both computers trying to use the same IP addy? That can cause something like you are seeing. I would manually assign a different static IP for each computer and see what happens.

 

just checked the router settings and ips are different for each of the comp.
At first i though downloads may cause such huge drop in speed. But a few days ago when itnernet was running smoothly, I could download file and do stuff without any significant diff. Actually a very similar thing happened to me when i had my brother's laptop at my house. I had used internet for 2-4days perfectly fine and then speed dropped dramatically. Couldnt resolve the prob, as i had to give back the laptop.
thanks for reply grumpy.
aany other ideas?

Not.

 

oh, darn...was hoping it would be something simple. So we have a situation where when wired and wifi client are attached at the same time the router slows down, right? When the wifi client is the only connection then it works OK? And when the wired client is the only onnection the speed is also OK?

I just looked up your router and it's a VoIP aware router. I personally have not worked with any VoIP routers before. I am wondering if you are not using the VoIP functions, can you disable them on the router then do a full power off cycle? This is simply to eliminate the function as the source of the problem. When you recycle the router I would power the computers down while the router is off also. Then bring up the router first then each computer on at a time waiting for the first on to attach before powering on the other. Also if you do have a VoIP phone connected turn it off and leave it off for now.

I have a few minutes today so I'll see if there is any input I can find out there in the ether...

 

Sounds more like a Driver issue with the Router. Make sure you are running the latest. And report the problem to Linksys, they may have beta fw for you to try. When it acts up drop down and run NetStumbler to make sure some one else not interfering with your setup. Someone may have 11n or MIMO knocking you out.

VoIP can cause problem. I had a friend have a Linksys router with VIOP and it would not open up the FTP port. He got caught in a Linksys and Spyke would not take responsibilty for the bug. Far as I know he still does not have ftp service.

 

Ill try both new fm and drivers and se how it goes.
By the way, i still get good speed when both computers are on, so i guess its more like random.
For example, I've had good speed for the last 2 hours now, with both computers running. Maybe its just ISP messing around. Ill keep you with the news,thanks for help

Ok my guess was right, it has something to do with wired compter, which somehow actually has an effect on my wireless speed.
Theres the situation.
I wake up, wired pc on, i turn on my laptop - wireless is barely working. I turn off wired pc and wuolia, wireless works just fine, then i turn wired pc back on and it still works fine. After all that sometimes smth happens and my wireless goes down again, then i need to turn off/on wired again. But sometimes it might work fine whole day. I really dont know how wired can have any effect on that. IPs are different, lapt uses 1.64 and wired 1.65 endings. Signalt strength doesnt change anything.
Any ideas how to find the issue? Would reinstalling wired pc OS help? if yes, what to do to avoid this again.

thanks in advance.

With combo routers you are sharing resources, ram, cpu, buss .... FW has a big play in this. Report your findings back to the MFG. Or it could be EFI Noise coming from that PC. Move it to a different location and see if it impacts it. Test with and without network.

It could even be a heat issue. I do not have a combo routers for the same reasons. Stand along has always out performed combo units.

 

Im not sure what do you mean by combo routers:/ We have 1 router, speedtouch wl 780, 1 pc and 1 laptop. Pc is wired and laptop using wireless.
And dont think its EFI noise, cuz if the wireless speed drops, i just turn off and turn on wired pc back and wireless gets back to normal.
Im not really sure if im explaining it well, but thanks for ur response and help

 

Combo are routers with AP, wireless routers. It sounds like you are having a firmware or heat problem in the router. AP generate a lot of heat. Have them inside the same enclosure as a routers and the heat is over doubled. If you have your router tucked in a small pocket, try moving it out in the open so it will get better air flow. If your router is set to log events, turn off all except critical. I have seen on a few routers that they had problems when the buffer started filling up. Doing a power cycle cleared all the buffers.

 

But if it was heat problem, wouldnt it take more time to cooldown after i shut down wired pc? Cuz affect is instant after it goes down. Router is more or less in open space under the table, there are loads of wires from/in pc/phone/modem/tv like 0.5m away from modem, could it be the reason. Btw router is put on the woofer, so maybe magnetic fields can interrupt it sometimes. Not sure which is relevant and cant go in and start moving thing around, as im just renting a room in this house, need to wait flatmate and try it in the evening. It just takes time, as connection problem occurs once a day, sometimes once every 2/3 days.
But all mentioned above and heat could lead to this issue.
Thanks, ill play around abit and see if theres any changes. Checked log section, there are about 30 logs in total, could it be significant enough?

 

The problem with logs is soon as you reset the router it dumps them from memory.

Are you using BT? You my have too many simultaneous connections.

 

Well i havent restarted router for a long time now, and if it was logs wouldnt internet speed be slow continuously.
I just got back home turned on laptop and net was off, while flatmate was using wired pc. As soon as he tunred off/on my net went back on and now we both can normally use internet.
ISP is Be, but im not sure whos behind them or it is independent ISP.

 

On my wireless card I can click the computer icon with radio signals coming from it in the taskbar,click properties then configure and then the advanced tab again.And Scroll thru the properties and see if you can tweak any of the setting to help you solve the problem. BTW my card is the 1390 mini wireless. You could try an ad-hoc network.

 

I was having the same problem. I have a 10mb line and only geting less then half that on my laptop. Desktop hardwired is fine. I think it has to do with regristy settings because I ram TCP Optimizer and now my laptop downloads at the same speed as my desktop.

Co worker had the same problem with his laptop at home and he tried TCP Optimizer and now it's better.

The short version:

1. Select your advertised maximum speed from the "connection speed" slider bar. (the maximum available bandwidth, in kilobits per second).
2. Choose your Network Adapter, or check to "Modify All Network Adapters".
3. Choose the "Optimal settings" radio-button near the bottom of the program.
4. Click "Apply changes", and reboot when prompted by the program.

The right version: Find your Maximum MTU value, learn what all the settings mean, and tweak them accordingly using The Optimizer in custom mode

Note: With version 2 of the TCP Optimizer, we've also included full online documentation

 

What a curiosity

Reading around the interweb, this router ain't the best, but its the one my new ISP gave me. Upto 24MB unlimited, but I'm content with 14-16 whilst testing 3-4pm, London. Then switch to wi-i from ethernet cable. Errr... Half that

But I have to say that TCP Optimizer is astonishing. Now back into double figures; 12MB on wi-fi but will have to call ISP tomorrow... hmm. Plenty fast enough but I would like closer to advertised (incidentally I have optimal connection to network)

Anyway searching for router as I entered new password for it, then it instantly denied me It was 2 seconds ago! Stupid thing. Forums were right. May have to reset it...
